The Cecil and Molly Smith Garden
Cecil and 'Molly' Smith were the founders and developers of what has become the internationally renowned Cecil and Molly Smith Garden. Cecil started collecting rhododendrons in the late 40s at their first home adjacent to the present-day Garden property near Newberg, OR. Cecil was a grass seed grower by trade...and originally owned much of the surrounding land. He became an early member of the American Rhododendron Society in 1947. In 1951 they obtained the garden property, finished their new house and started the garden. The area had been logged in 1915, but by 1951 had reestablished its growth of Douglas fir and native plants.
Cecil had grown up at Champoeg in the Willamette Valley and treasured the native plants. He also became interested in discovering the best genus Rhododendron had to offer. He eventually helped sponsor expeditions to the Himalayas, and participated in seed exchanges and experimented with hybridizing. His efforts were directed at what he thought were the most outstanding rhododendron characteristics: fine foliage and great flowers. A number of his crosses are found in the trade including, R. 'Noyo Brave' and R. 'Yellow Saucer'.
Cecil was very generous with his plants, sharing his cuttings, seeds, and pollen. He wrote articles for The Bulletin of American Rhododendron Society and his photos were used extensively.
Rhododendrons are the Garden's featured plants! Cecil was among the first to grow R. yakushimanum and used it for hybridizing. He was a "leaf turner" and loved the fine indumentum of R. yakushimanum and R. bureavii. He combined these two species and produced R. 'Cinnamon Bear'...the signature plant in the Garden.
The woodland Garden encompasses about three acres sloping gently to the North. Cecil took advantage of the slope and constructed paths that weave from top to bottom of the property. Decaying logs, tree stumps, and fallen limbs have been retained for their natural beauty. This accumulation of 'duff' provides most of the nutrients required and minimal fertilization is required. The Garden is weeded...because Cecil noted: "Unless a woodland garden is weeded, it is not a garden, but a wild area."
Molly's favorites were the Rhododendron 'Loderi' planted near the house and now are over 20 feet tall. Although never taking much credit for the Garden, Molly Smith contributed upkeep and maintenance in the Garden through the years. When the Smiths lived at the Garden, they freely shared their garden with others and hosted many garden tours. No one interested in rhododendrons was denied a visit in the Garden.
Cecil and Molly each received American Rhododendron Society Bronze Medals from the Portland Chapter, the highest award. Molly humorously commented that no one had ever before received a Bronze Medal for baking cookies! Molly was always the gracious hostess, welcoming her guests to her home and garden with freshly baked cookies. In 1967 Cecil was awarded the Gold Medal and in 1985 the Pioneer Achievement Award from the American Rhododendron Society.
In 1983, after more than thirty years of devoted stewardship, Cecil and Molly Smith reached a point in their lives where they could no longer care for the Garden. The Portland Chapter purchased the Garden when the Smiths made it possible by selling their land to the ARS at half of its appraised value. The Portland Chapter, along with the help of Willamette and Tualatin Chapters assumed its care and management. Cecil died in 1998, and Molly in 2007.
The Smith Garden has charmed and delighted visitors from around the world. Edmund Rothschild and his wife have visited the Garden many times along with other well-known Rhododendron enthusiasts. David Leach, author of Rhododendrons of the World, was a good friend of Cecil's, and enjoyed spending time in the wooded setting. Smith Garden has been featured in Horticulture magazine, and in the PBS television show Victory Garden. It is also included in The American Man's Garden by Rosemary Verey. Locally, every national convention of the American Rhododendron Society and Western Regional conventions held in the Portland area included tours of the Smith Garden. Mike Darcy has highlighted the Garden on his television show. Local newspapers and other publications have also included articles and photos of the Garden.
The native Douglas firs create an ideal environment for a natural woodland garden of rare beauty, featuring superior forms of species and hybrid rhododendrons. Complimenting the rhododendron collection are choice trees, shrubs, wildflowers and bulbs. Each pathway reveals its own visual treat...a moss-covered log with plants tucked in the bark crevices, plants thriving on tree stumps, drifts of wild flowers. Cyclamen, Narcissus, Erythronium and Trillium flourish here. The day-to-day work is done by a small group of volunteers with Fall and Spring work parties of the American Rhododendron Society chapters' members and friends.
Designing a Rhododendron Garden
For a rhododendron and azalea garden, plan the empty space first. With annuals or low-growing perennials, one's consideration is with the flower bed...but when plants grow tall...such as rhododendrons...it is much better to plan the open area because tall plants will make walls in your garden.
The open spaces will become "garden rooms". Consider traffic flow from one room to another...either by wide connections or with winding paths. Once you have defined the open areas, you are free to plant everything else...as flower beds! Consider how to treat the various spaces defined in the landscape. Should there be "open spaces" to enhance vistas, "corridors" for transitions between area, "closed spaces" for privacy, or "extensions" of the home interior? Consider movement between areas and access routes.
Design for easy care, avoiding plans that require heavy maintenance or constant pruning. Wide paths are better than narrow walks...since the latter often become tunnels over time. If the soil is poorly drained or plants won't grow easily, choose an alternative...such as mulched areas or slate.
Consider costs, too!
There are basic principles in designing. They are:
Form and Mass. The mature landscape should be in scale with its surroundings. Plants give the garden form, so mass plantings will be more effective than mixed groupings as gardens age. A planting of 5 to 10 azaleas of the same variety will look much better than a mixed planting as the garden matures since the plants will have grown together to look like one large specimen plant.
Line. Graceful and irregular curves are more interesting than straight line and sharp angles.
Color and Harmony. Choose colors and varying leave textures that go well together. Color schemes should be harmonious and compliment each other and any existing architecture.
Emphasis and Contrast. Place light colors again dark ones for emphasis. Include plenty of white and neutral colors to blend or provide transitions. For gardens with brilliant shrubs like azaleas and rhododendrons, it is wise to allow for at least 50% of the plants to be white or other soft tones to allow the eye to have a visual retreat from the more intense colors. In addition to white, pale pinks and yellows...such as those in some of the Knap Hill azaleas like 'Marina' are good blending colors.
Balance and Repetition. Informal, asymmetrical balance is preferred to symmetry since formal designs with shrubs become a liability over time. A large planting on one side of the yard can be balanced with a small but similar grouping on the other. Repeat colors and forms.
Unity. Everything should go together. The garden should enhance the home architecture and the community. Simplicity is desirous...but often difficult to achieve for a plant collector.
Choose varieties that will grow in scale appropriate for the landscape needs. Some azaleas and rhododendrons can be used as ground covers while others will be trees. Use dwarf varieties in the foreground or constrained places. Use large growers in the background or for screens.
Consider time of bloom. Some varieties flower very early and may need frost protection while others bloom late and might require more shade to extend bloom time.
Change the color scheme by selecting plants that bloom at different seasons.
Use many companion plants.
Visit Garrett Park, MD
Garrett Park, Maryland, located 12 miles north of Washington, D.C., is a small town (0.3 square miles of land, with a population of 992) famous for its Victoria houses, trees, and shrubs. The entire town is designated an arboretum, boasting more than 700 species of shrubs and trees, including a host of azaleas and rhododendrons.
Named for Robert W. Garrett, president of the Baltimore and Ohio Railroad, Garrett Park was laid out in 1887 along the lines of an English village. Much of the town is located in the Garrett Park Historic District, which is listed in the National Register of Historic Places.
In 1898 the town enacted legislation to preserve its sylvan setting by protecting its trees and shrubs. In 1977 Garrett Park officially declared the whole town to be an arboretum. Since then the Arboretum Committee has planted hundreds of trees and shrubs, including many rare and usual varieties, to maintain a canopy of shade and to provide color and botanical interest throughout all seasons of the year.
Phil Normandy, an arborist and member of the ARS Mason-Dixon Chapter, works part-time as Garrett Park's tree expert and cares for the 400 trees in the town's public space. Referring to the majestic sugar maples that were planted shortly after the town was founded, Mr. Normandy says, "Trees get better with age and some of these are essentially antiques."

Garrett Park is well worth a visit, especially in spring when the town's streets are a wonderland of color. Most home owners are avid gardeners and their landscapes are beautifully designed and well-maintained. If you love rhododendrons and azaleas this town certainly has many fine specimens. Put Garrett Park on your list of places to visit!
Oh dear, oh deer!
Like many American Rhododendron Society members, I share my garden with various "critters", including deer. Fortunately, the local deer don't like most rhododendrons, although they do like azaleas and evergreen azaleas, in particular, are akin to deer candy. I'm not able to fence the front yard (local by-lines and all that), so I've basically surrendered my front garden to the deer. As time has gone on, I've gradually switched many companion plants to things the deer don't seem to like. So, instead of Hostas, I now plant Brunnera - a lovely foliage plant with small blue flowers; the only tulips in the front are now in a pot on the porch, but I can plant snowdrops and daffodils. So, far, the deer have left the Crocus alone, so each fall, I add more of these. As well, for fall bulb colour, I find the deer haven't yet eaten Nerine or Schizostylus, but since these tend to be a bit pricey here, I've only planted a few of each so far, and I'm watching to see whether or not Bambi and his pals will eat them. Time will tell if these will work for me. Ferns seem to be generally deer resistant as do hellebores of all types. Hellebores make great companion plants for rhododendrons, having the added bonus of starting to bloom around mid-January in our area, with many new varieties having attractive foliage. The deer don't like anything with highly aromatic foliage, so in the sunniest areas, I've planted lots of lavender and I could put in some rosemary too. These may not be what generally come to mind as good companion plants for rhododendrons, but they seem to get along fairly well in my garden.
I've seen a couple of techniques that other local gardeners use to encourage the deer to move along. Two of my neighbours use motion activated sprinklers that are placed near their most precious hydrangeas (deer just love hydrangeas!). These seem to work well here, and I'm told that just the noise of the sprinklers starting is enough to get them to move. Other neighbours enclose small trees and shrubs with flexible plastic fencing material as a temporary barrier. And, some of the locals use various deer repellants (Bombax is very popular here). They spray their plants regularly in the spring to train the deer to keep moving by their property in search of something less stinky. Sporadic spraying is needed as a gentle reminder that the plants smell bad.
A great idea I saw recently was to put down wooden pallets on pathways leading from an unprotected garden area to the protected area. In this case, the plants in the back garden were much loved by the deer, but they could only access the area by going along a narrow pathway beside the house. The pallets act like a cattle guard and the deer just don't want to walk across the wooden slats. The gardener in question did say that the wooden pallets get very slippery when wet, but he can just up-end them while he is working, then pop them back on the ground as deer deterrents. Of course, the best deterrent of all is a good fence. Local recommendations say fences should be at least 8 ft high. However, most of us are able to keep the deer out with a standard 6 ft fence as long as shrubs are planted in beds beside the fence line. The theory is that deer need to be able to see an open space where they can land safely upon completing their jump. This certainly seems to work in our area: those of us with dense shrub plantings in a wide bed near our fences haven't had any problems with back yard gardens, but the neighbours with lots of lawns see the deer regularly.
It seems deer will eat anything if they get hungry enough, the trick is to make your garden less inviting than your neighbours. So, since deer don't like rhododendrons, you might as well plant lots! As if any ARS member needed an excuse to plant more rhodies!
Gardens East and West
Although my first job was with the rubber plantation industry in the then Federation of Malaya (now West Malaysia), I lived in houses provided by my employer, and had not yet become interested in gardening, and I now regret the opportunities I missed. However, I did fall in love with the people, culture and climate of SE Asia. After 8 years there, politics and personal reasons made it necessary to leave and return to the UK.
I went to Edinburgh, and the first garden of my own belonged to a ground floor flat (apartment) in a moderately salubrious part of the south of the city, only a five-minute car ride from the genetics laboratories where I was working for a Ph.D. The flat had a small garden area outside the front windows, only about 70 square feet, with a manhole cover over a drain access in the middle. Here was my introduction to gardening, a love that has grown over the last 35 years to become a consuming passion. I began (doesn’t everyone with no gardening background) with annuals - quick returns in color and scent. These rapidly lost their attraction, and, in view of my limited space, I turned to alpines. I even made a garden in a cement bowl, to put on top of the manhole cover! I think my rock garden must have been one of the smallest ever, and my enthusiasm for acquiring new plants rapidly outgrew the space available. I can remember working round the garden by torchlight (like most postgraduate students, I was working all the hours there were in the lab) trying to plant something without digging something else up. Also, despite the poor soil and vicious climate, plants persisted in outgrowing their allotted space. Something would have to be done. Fortunately, this episode coincided with the completion of my Ph.D. and submission of the thesis. I could now look for a job.
The Medical Research Council (MRC) offered me a post as a research scientist in its Clinical and Population Cytogenetics Unit (now called the Human Genetics Unit) based in the Western General Hospital in Edinburgh. On the strength of the offer, I started to look for a house with a proper garden. This I found about 7 miles south of Edinburgh, in a village called Eskbank. The fact that the MRC unit was on the north side of the city, requiring a commute across the city twice a day, seemed less important than that the house had a garden of nearly an acre, which had been almost totally neglected for about 3 years. The garden was entirely surrounded by a high stone wall, and I immediately had visions of all the exotic trees and shrubs I could grow in that sheltered space. There was also a conservatory on the north side of the house, and a lean-to greenhouse on the south-facing wall of the garden. The climate in that part of the east of Scotland is cold and dry. Frosts can occur in 10 months of the year (only July and August are reliably frost-free) and it has been known to snow in mid-June! Rainfall is low, only 25 or so inches per year, falling mostly in the winter months, and there are frequent cold winds. Temperatures in the worst years, like 1981-82, can go down to -17°C (0°F).
Tall privet hedges (so high they had to be cut from a stepladder) divided the garden internally into three areas. The front garden, to the west of the house, had two broad areas of lawn on either side of the gravel drive, with a broad bed down the north wall. Then there were the "side garden", to the north, and the "orchard" separated from the rest by a concrete path, on the south of which was one of the hedges, with another tall wall on the north. The side garden had a small lawn, but much of the space was occupied by a raised area (perhaps intended for a pool), on top of which 2' X 2' concrete slabs had been laid, alternating with open squares of earth, to make a chess board. Hybrid tea roses had been planted in the open squares, adding further to the Alice in Wonderland effect, though most of the roses had died. The remainder of the garden was largely choked with scrubby Michaelmas daisies (I really don't like most composites). When these were cleared, it revealed a vast quantity of snowdrop and Chionodoxa bulbs, so many they had been pushed out to lie on top of the soil, which augured well for the success of other bulb species.
The raised area was the first to be tackled. Rather than try to remove this structure, I took away the concrete slabs, added quantities of gravel and turned it into a raised bed, to form the center of a rock garden, building up screes and cliffs around the perimeter. I thought that alpines would do well in the local climate. I started with the commoner sorts - Aubrieta and so on, but rapidly became enthused by dwarf bulbs and corms - Narcissus, Tulip, Crocus, Cyclamen, Iris and Galanthus. I also grew a lot of gentians, and primulas, both alpine species on the rock garden, and the beautiful Barnhaven polyanthuses for the ordinary garden beds. Right at the top of the rock garden, against the wall, several species of Juno iris (I. magnifica, orchioides, bucharica) survived for several years, but never increased.
By this time I had been introduced to the Scottish Rock Garden Club (SRGC), whose members were generous both with plants and advice. I am especially grateful to the late Dr Simson Hall, who was not only a keen rock gardener, but also passionate about all flowering shrubs and bulbs, and in particular rhododendrons. It was he who introduced me to the late Euan Cox, founder of the rhododendron specialist nursery Glendoick Gardens, and in turn Euan was happy to take me on guided walks round his beautiful woodland garden outside Perth. My rhodoholicism started with the dwarf species and hybrids grown in and around the base of the rock garden and neighboring areas. These began with the Lapponicums, like R. russatum, scintillans, microleucum, chryseum and hybrids, 'Blue Diamond' and so on, which I was sure would be hardy in the east of Scotland. But I soon (as do we all) began trying to push the limits of what I could grow, so added species like the beautiful R. moupinense (always one of my favorites in all its color forms, white, apple blossom pink-and-white and rose pink) and hybrids like 'Cilpinense', as well as its other parent R. ciliatum, plus the gorgeous R. yakushimanum. You will notice, I am still using the older names - I don't have the energy or mental agility to learn a whole new set! Many rhododendrons, like R. leucaspis and its hybrids, though perfectly hardy in themselves, flowered so early that their flowers were destroyed by frost almost every year.
I planted a whole lot of dwarf conifers, and the ease of these and the dwarf rhododendrons made me consider a suitable plan for the remaining section of the garden - the so-called orchard. This was an area of about a quarter acre containing a few old and diseased apple trees in rough grass, with a row of large lime trees (Tilia europea) down the west border, backed by a brick wall. With the help of Joe Sharp, an ex-coal miner (most of the mines in the district had closed) I cleared the apple trees, trimmed the grass, and erected a chain-link fence across the eastern third of the area. This included a lean-to greenhouse against the south-west-facing wall), and I intended to use this part for fruit and vegetables. The remainder would be a tree, shrub and bulb garden. I had already learnt that herbaceous plants take a deal of care, for which I could not spare the time. I made an exception though for hellebores, as their rich and somber flowers are so rewarding in the depths of winter, and last for weeks. Reading Jan de Graaf's books had fired an enthusiasm for lilies, and I was growing many of these, as well as rhododendrons and other plants from seed. Much of the seed came from the various seed exchange schemes - Alpine Garden Society, SRGC, ARS and so on, but I had also collected berries of many Sorbus species from the arboretum at Westonbirt while on a fall holiday. These were very successful, and fruited early and regularly, as well as providing fine fall color.
My rhododendron collection had already expanded to include all the Cinnabarinum and Triflorum species and hybrids I could find (I believed these would be best suited to the climate, and I love the Cinnabarinum flowers and foliage), as well as several clones of R. edgeworthii (the only reliably hardy Maddenia). I even tried some of the large-leafed species like R.fictolacteum, but they were never happy, even when I could give them a shady position. Just too dry for them. However, a number of Thomsonii species did well in the shade of the lime trees. These included the lovely bowl-shaped R. soulei and R. callimorphum and the yellow R. wardii in several forms. In the open areas I planted all the sweet-scented deciduous azaleas I could get - R. prinophyllum, R. nudiflorum, R. viscosum, R. luteum and R. atlanticum, and as many clones of R. occidentale as I could find.
Then Graham Stuart Thomas's books on shrub roses started me on another collection (especially of the yellow species and near-species like 'Canary Bird', R. ecae, R. X cantabrigiensis and so on), and I got keen on willows, and Camellias and Rubus and tree and herbaceous peonies and honeysuckles, and, and...You know how it happens. Anyway, after about 5 years the garden was getting pretty full. The walls were almost completely covered, with a Mermaid rose having the north-facing wall to itself -the thorns were too vicious to try any pruning: once inside their clasp and you would never escape! The fruit and vegetable section was also well stocked by now - a peach and a nectarine in the greenhouse, and espaliered apples, plums and pears along the wall, strawberries and raspberries (very successful in Scotland) as well as gooseberries and blackcurrants, and even some exotic varieties of potato.
The conservatory on the north side of the house proved ideal for seed raising, but had insufficient light and ventilation for my alpines and bulbs. I built an alpine house (using the concrete slabs taken from the rock garden as footing) in the side garden. This had the great advantage that I could be dry while caring for my plants, and the summer dormant bulbs could be left to bake in comfort if I had to go away. Two hot dry summers, and correspondence with the Aril Group of the American Iris Society (by snail mail - this was before the days of email for everyone) encouraged me to try some of the desert irises of the Oncocyclus group. I built two raised frames (stealing ground from the vegetable patch) and got plants from Israel. The flowers were spectacular, huge things in reds, purples, browns and silvers, with a few pinks and yellows, and they did wonderfully well for a couple of years, but then the weather pattern reverted to its normal showery dull cool summers, and they gradually rotted away. A few of the Regelio-Cyclus hybrids survived for another 9 or 10 years, but never flowered at all freely and when I moved house into town, I gave them to friends in the south of England, who I hope have had better luck with them.
The bitter winters of 1981-82 and the following year, which felt as if we were entering a new ice age, and killed many of my more tender plants, made me realize the problems of commuting in snow and ice. This, plus the cost of heating a big Victorian house, caused me to seriously consider the possibility of moving into town, and I finally surrendered two years later.
The next garden was a reversion to an ordinary suburban plot, though with more space than my very first garden. I moved in a snowy January, with the ground hard frozen. Despite this, I tried to move some of my hellebores and the smaller rhododendrons, and even hunted for the more precious bulbs, though the earth had to be broken with a pickax! I managed to salvage some of the better things, and they sat in the garage until the earth thawed sufficiently to let me plant them. It took a couple of years for me to adjust to the small space, and I still kept bringing home shrub roses that outgrew their space in a season! Eventually I was back to dwarf rhododendrons and bulbs, with my surviving hellebores in among them. One of the most successful rhododendrons was 'Dora Amatais', which flowered regularly every spring, with flowers that withstood several degrees of frost.
This was the period when I started visiting gardens seriously, as my own took less time to care for. There are many gardens in Scotland and England, both privately and publicly owned, open either year round or on specific occasions, and nearly all are worth a visit. I took holidays in the west of Scotland, in Argyll and Sutherland, visiting places like Glenarn, Arduaine, Gigha and Benmore (an outpost of the Edinburgh Royal Botanic Gardens, RBGE), and later started going to Ireland, particularly the southwest, Cork and Kerry. Here the summer climate was perfect, the landscape idyllic, and the gardens spectacular, and I resolved to look for a house with some land for my retirement. I was encouraged by visiting gardens like Ilnacullin (Garinish) in Glengarriff harbor on Bantry Bay, where the Maddenia rhododendrons scent the whole island in May and June. Fota, near Cork City has a fine arboretum full of tender trees, and Dereen, on the Kenmare river, north of the mountains between Cork and Kerry, has tree ferns better than I have seen them anywhere since the Cameron Highlands in Malaya!
I moved to my 200-year-old farmhouse, with 3 acres of rough bog and grassland 50 miles west of Cork city, in June, towing a trailer full of plants in pots and plastic bags. It was raining when I arrived, and the wind was a cold north-eastern. It barely stopped raining and blowing for the remainder of the year. I managed to get some clearing and planting done round the house, but the bog-land behind the house, with a stream running through it, which I had planned to drain and plant with trees, opening the stream into a pool, remained too wet for any machinery to get in there. The gales steadily increased in frequency and violence, and at Christmas so many trees and power lines were brought down that I was without electricity for 5 days. Fortunately I had a gas cooker, but for water I had depended on an electric pump from my 100 ft well. My neighbors to the west were farmers, with a generator for their pump and milking parlor (this is a dairy-farming district) and supplied me with water by the bucket, as well as inviting me to share their Christmas meal. Good people.
The following spring continued the same pattern of weather, and, having come here to escape the cold of Edinburgh, I felt I had wasted my time. I decided to cut my losses and head back to SE Asia, where I knew I would be warm. Malaysia has changed a great deal in the 30 years since I left, and I knew something of Thailand, so decided to try there instead. That was more than 3 years ago, and I am still here, and still content.
The climate here in Phuket, while similar to that of Malaya (a further 500 miles south) is very different from that of central and northern Thailand, as well as from Europe, and some westerners (farang as they are called here) find it unbearable. It is hot, and, for much of the year, humid. Daily temperatures range from a minimum of 20°C (68°F) in the cooler season (January) or 25°C (77°F) the rest of the year to a maximum of 35°C (95°F), or, on one or two days last month, 37°C. For comfortable sleep you need air-conditioning, but we don't find we need it during the day, unless we have visitors.
We get rain all year round, with peaks in the monsoons in May-June and September-October. During the monsoon seasons we get occasional days when it rains all day, but most of the time even then we get heavy rain showers (sometimes with thunder and lightning) interspersed with warm, sunny periods. Outside the rainy season we get a heavy rain shower once or twice a week - enough to keep everything growing well. Even when it rains, it is never cold! The annual average rainfall is about 90 inches, and we get around 8 hours sunshine a day from November to May, falling to 4-5 hours a day in the rainy season. Further north they have a different climate, with distinct wet and dry seasons. They only get half as much rain as we do, but it all falls between May and October. In the wet season they have floods, and in the dry season the hills burn, lit by sparks from burning rice stubble, carelessly thrown cigarette stubs, charcoal burners' fires, picnickers or even deliberately set, to clear forest for planting. In the wet, it is hotter than here, with temperatures sometimes passing 40°C (104°F), while in the dry it can be cooler than here. In the high mountains of the north, temperatures at night in January can occasionally go down to near 0°C, and frosts are not uncommon. However, the general run of night time temperatures on top of Doi Inthanon (Thailand’s highest peak at 2565 meters, 8000+ feet) don’t go much below 7 or 8°C (46-48°F) though that feels very cold after living in the south!. Daytime temperatures in January run up to 20-30°C (68-86°F) and in July go very much higher.
The soil here is abominable - sticky clay on top of broken laterite rock. Phuket was a major tin mining area, and most of the housing developments are built on the spoil from the mines, with the dredge pools converted into ornamental lakes and water reservoirs. Despite this, it probably won't surprise you to learn that any plants that tolerate our climate and soil grow VERY FAST. I have grown coral trees (Erythrina) from seed sown in January 1999 that are already 20 feet high, with a canopy as much across. Peacock bushes (Caesalpinia) also from seed sown at the same time, have to be cut back every 3 or 4 months and this only stops them flowering for a matter of a week or so. Fiddlewood trees (Cytheraxylon) from 12-inch cuttings are now 12-15 feet tall and covered with tassels of sweet-scented white flowers, loved by sunbirds (the Old World version of humming birds) and huge birdwing butterflies. I could extend the list, but you get the idea.
The ideal rhododendrons for this climate are, of course, the Vireyas, but there is not a single nursery in Thailand that supplies them. Mind you, that is not such a surprise, because the general run of nursery stock is limited to the standards - Bougainvillea, Canna, Allamanda, Hibiscus and assorted palms. The one garden in Thailand that grows Vireyas in quantity is the royal arboretum at Mae Fah Luang, right up on the northern border with Burma. Their plants (some 20,000) were all imported from Australia, but they tell me they do have plans to propagate for sale in a year or two. My plants have also all been imported, from nurseries in Australia, Oregon and Hawaii. I am very grateful to those who have been willing to take on the hassle of dealing with Agriculture Departments (described by one nurseryman as "Gestapo") to get phytosanitary certificates for export, in return for small orders.
I am pleased to say that nearly all of them have survived the trauma of the journey and are alive and growing well. They are all in pots, and I have to consider what to do when they outgrow their containers. The best plan will probably be that used by Mae Fah Luang, where they plant them in shallow saucers, spreading the roots out, and covering with a mulch of pine needles. Here we might have to substitute Casuarina leaves for pine needles, as there are no local pine trees. In the pots they grow in a mix of coconut fiber chunks with perlite, pumice and broken brick - very free drainage! I have also tried a few of the Thai native species, which all grow on the northern mountains, at upwards of 1400 meters. Some have survived and are growing, like R. arboreum, R. lyi, R. simsii and R. surasianum, but others are looking unhappy (R. moulmainense), and some (R. pachypodum) and non-natives (R. nuttallii) have already died. They survived, and even opened new leaves, until the heavy rains started in May, when the leaves started to brown and fall, so it seems to be the humidity that they don't like, not the heat.
However, I now have some 40 Vireya hybrids and species, all growing well and apparently healthy, apart from the depredations of a particularly nasty beetle, about 1-1½ inches long, yellow and gray, which loves to chew holes in newly emerging leaves. There is also a rather unpleasant caterpillar, only ½ inch long, that sticks the leaves together while they are in bud, and lives happily inside, eating away, until the outer leaves open, and reveal a mess of dying leaves inside, and a dead terminal bud. If terminal buds are going to get removed to encourage branching, I prefer to do it my way! I don't really bother much about ordinary caterpillars; they don't do a lot of damage, and they are going to turn into the lovely butterflies and moths that decorate the garden. Some of the caterpillars are quite spectacular in their own right; those of the Atlas moth (a huge cinnamon, pink and silver beast, with a wingspan of more than 8 inches) are about 6 inches long, and a glistening silvery-white. They feed on the leaves of the torch gingers, Etlingera, which always have more leaf than flower!
Other plants that have proved successful are all the Bauhinias I have tried: B. purpurea, B. variegata (in several color forms) B. acuminata, and B tomentosa (only the plain yellow one so far, but I hope to get the two-colored one eventually). My favorite so far is a form of B. variegata of which I collected seed near Mae Sai, on the northern border with Burma. It has pure white flowers with a pink flare on one petal, very strongly and sweetly scented. One of the many attractions of the Bauhinias is that they flower within a year from seed.
I also grow about half a dozen different jasmines. I love all scented plants, and the jasmines are among the best. I am still looking for seed of Jasminum revolutum (humile), the shrubby yellow scented species. I have a lot of climbers (including some of the jasmines) and one of the best is Odontadenia which has long creamy yellow buds, opening to 6-inch trumpets, apricot in the lobes and peach-orange in the center, with a beautiful scent.
Several Passiflora species also do well, and Quisqualis (Rangoon Creeper), with flowers that open white and change to red, needs to be kept in check. Scented shrubs include several Gardenias, Murraya paniculata (Orange Jasmine, Chinese Box) and Wrightia religiosa, as well as a lovely small tree, Millingtonia hortensis with the dull name of Indian Cork Tree. This really ought to be called a tree jasmine, as it has 3-4 inch long tubular creamy white flowers, with a delicious scent.
Pests other than those I have mentioned are fairly few, though fungus diseases are always a risk in the high humidity. There is a rust that attacks the frangipanis (Plumeria) but doesn't seem to bother anything else, and a pink and white fungus that grows on the stems of Hibiscus mutabilis, as well as some that cause leaf-spotting on several species (Phytophthera?). There are other pests that bother people of course - mosquitoes (only at night out of doors) and the odd snake. We had a 5-foot cobra in the garden yesterday morning. The dogs had cornered it and were barking their heads off, and the poor beast could not get out through the dog-proof wire netting. A pity, as we had to kill it (it made a meal for some neighboring gardeners), and I prefer to live and let live. Snakes don't bother you if you don't bother them, and it was only its inability to escape that made it a danger. So all in all, Phuket is a very satisfactory place to garden, though I would like to be able to grow some of the more temperate rhododendrons, and the deciduous azaleas. Still we always hanker after something we can't grow, otherwise we would be moribund, if not dead!
Those Pesky Labels!
When I first started growing Rhododendrons, I just had a few plants so it was easy to remember their names, but as my collection has grown, I find myself trying to remember which plant is which, and this has started my love/hate relationship with labels.
I think all gardeners want labels that are inexpensive, that last forever, stay in place and do not harm our plants. And, since we don't want to see little white stakes all over the garden, which is just too reminiscent of a cemetery, we want something that is unobtrusive as well. Finding something that fulfills all these wishes is hard and I don't think anyone has designed the perfect label yet.
The plastic, ribbon-like tags that come with most garden centre plants these days last a long time, but the print fades fairly fast and they can girdle the plant stem they're attached to if you happen to forget to loosen them periodically Anyway, they don't look very nice in a garden setting
There are several problems in using plastic, stick-type labels. First, you have to find something to mark them with that doesn't fade over time. Permanent marking pens like the Sharpie pens school children use are o.k., but the ink eventually fades. I find a lead pencil works just as well as a marking pen and usually outlasts the "permanent ink" writing. In addition to looking a bit like grave markers, the stick-type tags don't work very well for long-term use because they become brittle and snap after a couple of years. I've had to piece together old broken tags to decipher plant names on several occasions. And, finally, tags just stuck in the ground are tempting targets for pranksters to pick up and move around. This is a problem in one of our local public gardens. Pranksters don't have to be human either - one Spring, I used stick tags to label a new collection of daylilies. The crows just loved the tags and pulled them out of the ground. I found tags all over the place - repeatedly! Fortunately, I'd made a map of where various daylilies were planted so I was able to re-tag the plants correctly. Wooden tags (some gardeners use popsicle sticks) have all the same problems as plastic ones, plus the wood rots or splits, so this isn't a good permanent solution to the tag problem
My own favourite labels are the soft aluminum tags where an old ball point pen is used to "engrave" the plant name into the metal. These are attached to plants with a twisting wire. They aren't too bad, except the wires can girdle plant stems if not loosened periodically. If you use these, make sure you press hard when writing on the plant name because in time, it can be hard to read the "engraving".
One couple in our local ARS chapter have beautiful tags made of cut up aluminum gutters. They use a Brothers P Touch machine to create labels that have a glue-backing that sticks well to the aluminum. The tags are long lasting and easy to read, but I don't have a supply of aluminum gutters around, nor do I have the right kind of saw to do the cutting, and even if I had both, I think I'd be too lazy to make them. I do like getting plants from them though because in addition to growing lovely plants, their labels last for years.
Some people advocate putting a label underneath any plant that is going in the ground at planting time. Either plastic or metal would be o.k. for this. The idea is that if the above ground tag is lost and you can't remember what the plant is, you could, at least in theory, dig up the plant and check the label. I do know people who "plant labels", but to me, this is one of those suggestions that sounds o.k. in theory, but is impractical in the real world. Can you see yourself trying to dig up some big Rhodendron Loderi to find the label? However, I do slide an extra label down the side of all of my potted plants as these tags are fairly accessible in a pinch
As a failsafe method, I try to keep a map of my garden beds showing roughly where I’ve planted things. This is useful as long as I take the time to update the map periodically. For some reason, I find it easier to move a plant than to change the map record. A couple of friends who are rock garden enthusiasts showed me their most recent method of keeping track of their plants. They take digital photos of a bed, then using Power Point, they label all the plants in the image. This seems like a good idea although there is still the issue of actually getting around to updating any changes.
One thing for sure though is to watch out that tags that are wrapped around Rhododendron stems do not get too tight. Every now and then, take a tour around the garden and loosen up wires or ribbon-like tags. Happy labeling!
Early Blooming Rhododendrons
While it's still early January, I've started to watch for Rhododendrons in bloom. Here in the Pacific Northwest, there aren't many yet, but I've seen a few brave trusses of what I think are 'Christmas Cheer' and 'Nobleanum'. Since the plants I see belong to someone else, I have to guess at the varieties.
The pale pink flowers of 'Christmas Cheer' look so delicate, but this is a tough hybrid. With mild winter temperatures, the flowers last for weeks although one hard frost will damage them. On the plant that I think is 'Nobleanum', the flowers are rounded balls of deep rose pink. I can't get close enough to the plant to see if there's a flush of white in the flower centers, but this would be typical of the variety. 'Bo Peep', another very early hybrid I see, is also just about to bloom. This small yellow flowered plant won't win prizes for showiness, but how can you not like anything that is in flower now.
In my own garden, 'Seta' is the earliest of my rhododendrons to bloom. I just love this hybrid. The flowers are tubular: light pink inside with dark pink backs. 'Seta' is loaded with flowers every year, and blooms reliably for me by mid-March. I have one 'Seta' in a large container that I move onto the deck when it's in bloom and I like this variety so much that this past fall, I planted another one in the garden.
'Snow Lady' is another of my early favorites, and it also blooms for me in mid-March. In addition to lovely white flowers, the leaves are hairy, adding another interesting dimension to the plant. The leaves are particularly pretty when there's a bit of dew on them. I grow 'Snow Lady' in a container, and it looks great when placed next to 'Seta'.
Both 'Seta' and 'Snow Lady' tend to get leggy, but who cares! They're great harbingers of spring. I could pinch them back a bit after blooming, but I like their open habit.
If you like the look of these varieties, another variety to look for is 'Cilpinense' (photo right). Another of my favorite early bloomers is R. mucronulatum 'Cornell Pink'. I like the pale pink flower color, but many people in our area prefer the more intense fuchsia-pink flower of 'Crater's Edge'.
Some of the species that bloom early for us in our area are super plants. R. dauricum, R. moupinense, and R. strigillosum all bloom in late winter or very early spring. R. dauricum covers itself in small flowers of either intense fuchsia-purple/pink or pure white flowers.
R. moupinense is a hardy pink flowering rhodie. The species has white flowers with small, red blotches. If you like red, then R. strigillosum is for you. This is a stunning early bloomer. In addition to the lovely flowers, R. strigillosum has hairy bristles along young stems, which are very pretty, especially when backlit.
To give yourself the longest possible chance for blooms to persist, you need to locate early blooming plants in an area where they receive some overhead protection from frost. My neighbors actually cover their 'Christmas Cheer' at night with a blanket if hard frost is expected during blooming time. By doing this, most years they are able to keep the plant in bloom until mid to late March.
We are all looking for that blue rhododendron, but last time I looked all of the ones with "blue" in their name had purple flowers. 'Blue Admiral', 'Blue and Gold', 'Blue Angel', 'Blue Baron', 'Blue Bird', 'Bluebell', 'Bluebird', 'Blue Blood', 'Blue Boy', 'Blue Chip', 'Blue Cloud', 'Blue Crown', 'Blue Danube', 'Blue Dawn', 'Blue Diamond', 'Blue Effect', 'Blue Ensign', 'Blue Flame', 'Blue Frost', 'Blue Girl', 'Blue Hawaii', 'Blue Haze', 'Blue Heaven', 'Blue Horizon', 'Blue Ice', 'Blue Jay', 'Blue Lady', 'Blue Lagoon', 'Blue Light', 'Blue Mist', 'Blue Monday', 'Blue Moon', the list goes on and on. It is obvious that the hybridizers wanted blue, but alas, the blue gene is not to be found in the genus Rhododendron.
Mind you, some of these rhododendrons are nice plants, but their flowers are definitely not blue colored. I am even responsible by naming a hybrid 'Amiblue'.
So, let's look beyond the flowers, they are only visible for a short time anyway. How about foliage? There are many rhododendrons with blue leaves, well almost blue, closer to dark greenish blue, but quite evident in the garden among the other shades of green.
My favorite blue rhododendron species are: R. campanulatum ssp. aeruginosum, R. clementinae, and R. lepidostylum. I am sure there are many other also, but those are the ones I have in my garden. These are generally not found in your local garden center, but are available from many specialty rhododendron growers, such as the Rhododendron Species Botanical Garden.
I am sure some of you may have other blue rhododendron ideas, and I welcome your comments on this blog.

Flower Show Tips
Lots of flower shows are coming up, and it's fun to enter Rhododendron trusses and plants. If you're after winning, there are some "tricks of the trade" that help. First of all, you have to read the instructions for the show. That's where you find information about the time to place your exhibits, how they are to be presented and the different show categories available. Once you've got that information, start watching your plants for likely candidates. I like to keep an eye on things starting about two weeks ahead of a show, but in the end, it comes down to what looks good on the day entries are picked to be entered. Often, the "perfect" truss is not quite ready or too far gone. C'est la vie in the world of flower shows.
With trusses, if at all possible, choose one from the top of the plant so that the truss is full and balanced on all sides. Sometimes there isn't any choice available and you have to take one from the side of the plant, but if this is the case, take the fullest truss you can find and the one with the most flowers possible. Most of the flowers should be open, but if the topmost buds have good bud colour even though they haven't quite opened, that's o.k., and in some cases can work to your advantage. Usually you have to place your entries in a show anywhere from 6 to 12 hours before the actual judging happens, so the topmost buds might open while sitting on the show table. Hopefully the show hall will be cool, but sometimes it isn't, and then you're faced with having a truss that's too far past its peak by the time the judges come along.
To prepare, each truss needs careful grooming. I use forceps to remove any bits of bract that may have fallen in between the flowers. When it comes to leaves, it's really nice to have a ring of leaves up near the flowers, sort of like a green collar. But, sometimes the leaves are ratty looking and then there's the conundrum of whether to remove them or not. Before snipping, I like to check the show catalogue to see if there's any statement about leaves needed in the presentation or not. Then, depending on what's permissable, sometimes I leave them on, sometimes I remove them.... it usually comes down to a gut feeling at the moment as to what will make the truss look its best, but generally, judges like to see some leaves. The base of the stems get cut on a sharp angle and immediately inserted into tepid water. Fresh cut stems absorb warm water faster than cold water.
Different groups use different containers for their shows, so... read the show instructions. You at least need to balance the vase size with the truss size and you also have to come up with some way of getting the flowers to sit up-right in the vase and not flop all over. Locally, lots of us use clean beer bottles, labels removed of course, (and if you need bottles, it gives you a good excuse to drink beer). These work well for fairly large trusses since the bottles are heavy enough to sit securely on the bench and the narrow neck holds the stems up-right. Sometimes though, the trusses need a bit of help and something has to be inserted into the neck of the bottle to hold the stem in position. Anything you can think of that is unobtrusive is good. Some people use small bits of florist oasis, others use wine corks that are sliced in half (an excuse to drink wine) - use whatever you can think of. Trusses of the small rhodies can get lost in a beer bottle, so look around for little bottles (old spice bottles aren't bad), and again, get the trusses inserted into water quickly.
Trusses need to be labelled and put into the correct class. Fill in the information needed for each entry and hopefully you know the correct variety name. However, if you don't, just make sure the truss goes into the right category, like red flowered, or trusses under 6 ", where ever it fits. Sometimes someone will recognise your unknown variety and identify it for you. As well, there are usually people around to help you figure out where to put things - just ask. That's all there is to it. The judges do the rest of the work and you get to come back later to see a hall filled with colour, and maybe you'll come home with a ribbon or two.
How I Became a Rhodoholic
I guess I'm a rhodoholic, at least that's what my friends say. I became afflicted when I moved to the Seattle area back in 1956. I came from the dry, cold side of Washington State where I had never seen anything like Rhododendrons. It seemed like every home in Seattle had at least one if not more Rhododendrons. I was fascinated with the bright, showy flowers of these evergreen shrubs.
The most popular Rhododendron was 'The Honorable Jean Marie de Montague' (most people just called it Jean Marie). I couldn't stop there, I got a 'Blue Peter', then 'Taurus', and 'Nancy Evans' and 'Trude Webster' and the varieties seemed endless and I wanted them all. Then I noticed that the species Rhododendrons had interesting leaf shapes and a fuzzy coating underleaf called indumentum and sometimes a coating on the top side called tomentum. So I had to have R. pachysanthum and R. bureavii, and R. pseudochrysanthum.
I was obviously hooked! I joined the American Rhododendron Society and started attending the meetings of the local chapter in Seattle. That just added to my affliction as I got to know others with like interests. Ther was so much to learn, so I had to get books about Rhododendron culture. The book that was recommended was Harold Greer’s Guidebook to Available Rhododendrons. Then I discovered Peter Cox had published a whole series of books on cultivation of Rhododendrons and I got them all.
My association with The Seattle Rhododendron Society (SRS) included volunteering to help maintain their Rhododendron Garden on Whidbey Island, Meerkerk Rhododendron Garden. This is a 51 acre garden that was bequeathed to the SRS with the purpose of allowing the public to observe and learn about Rhododendrons and companion plants. I eventually quit my job at Boeing to become the fulltime manager of Meerkerk. Mrs. Meerkerk had planted many hybrid and species Rhododendrons, but the gardens had not been adequately maintained for many years and needed some tender loving care. The goal was to make it a test and display garden to attract people interested in Rhododendrons, both local and tourists. My wife Mary and I set about clearing the wild brambles and weeds that had all but taken over.
My interests gravitated toward hybridizing and my job at Meerkerk provided the many sources of pollen to accomplish that role. I started growing my own hybrids and evaluating them for quality, hardiness, and susceptibly as a garden plant.
After 6 years at Meerkerk, Mary and I decided we needed a place of our own and found and purchased a 15 acre wooded lot not far from Meerkerk. We now have a home and garden of our own where we can continue exploring the virtues of the genus Rhododendron. I hope this affliction never ends because there is so much to learn.
Spring Has Arrived
It's late March, and finally, spring has arrived in local gardens. Here in the Pacific Northwest, we've had a troublesome winter - not difficult compared to much of North America - but with a couple of episodes of sudden cold spells that have led to some winter injury. The really damaging cold came in late November, when temperatures dropped suddenly to -8 C after a mild, wet fall. Lots of plants were still actively growing at the time, so hadn't hardened off properly. We had a second cold snap here in late February (again to -8 C), but since plants were still dormant, this didn't cause many problems. It was the early cold that hit things hard.
As spring arrives, I'm relieved to see that most of my rhododendrons will be o.k. although there is some flower bud damage here and there. Most surprizing to me is the bud injury on my R. 'Nancy Evans', a variety usually considered to be an easy grower here. There will be flowers, but perhaps not the usual "knock em dead" display.
The plant I'm most worried about is my R. lyi, which has lost a lot of leaves as well as its flower buds. However, R.lyi isn't really hardy here, so growing it for me has been a case of zone denial. I'm hoping for regrowth from the lower part of the main stem and of course, if it does die, there's always the thought that there's now space for a new plant. Hmmm, we'll see.... So much for the sad news, we gardeners are really optimists, and most things will be fine and the spring displays great.
Rhododendron lutescens, one of my favourite species, is out full today, adding a soft, cheerful note to the garden. If you like pale yellow, this early-blooming species is reliable, easy to grow and readily available, at least in our neck of the woods. I've planted a fair number of daffodils in the same area, and there's tons of Muscari (grape hyacinth) coming up too, so the yellows and deep blue/purple really draw the eye to that part of the garden.
