Variegated Evergreen Azaleas

Until recently, there were very few variegated evergreen azaleas available in the United States. These include the Satsuki varieties:

• ‘Keigetsu’. One of the earliest blooming Satsukis with light pink flowers and a red margin. The green leaves are flecked with white on a low spreading plant.

• ‘Uki-nishiki’. White flowers with many variegations of stripes, flecks, etc. of a dark purple. The leaves are flecked with yellow.

• ‘Shira-fuji’. The flowers are variable, generally white with purple variations. The leaves have an attractive distinct white margin on a dwarf plant.

• ‘Shinyo-no-tsuki’ sport. Very large white flowers with crimson blotches that bloom in June. The leaves sport cream stripes longitudinally throughout.

• ‘Fuji-no-mine’. A dwarf cultivar admired for its unusual foliage, the leaves are variegated with many flecks of yellow. Pink flowers with a darker circle that bloom in June.

American growers began introducing variegated azaleas in the late 1980s and early 1990s. One of the most popular and now widely available is ‘Silver Sword’, a sport of ‘Girard’s Rose’ with a distinct white margin bordering a dark green leaf. Other Girard plants with white margined foliage included ‘Girard’s Variegated Gem’*, a sport of pink-flowered ‘Girard’s Border Gem’*, and ‘Hot Shot Variegated’* with bright orange-red flowers. These varieties tend to have a lighter green color in their leaves.

Two southern varieties of the white-margined types discovered in the 1980s are ‘Southern Belle’, a sport of ‘Pink Ruffles’, and ‘Red Ruffles Variegated’. Another lovely choice is ‘Silver Streak’, a Greenwood hybrid with white-margined foliage and purple flowers; it is a sport of ‘Deep Purple’.

Finnerty Gardens

Finnerty Gardens has one of Canada's best collections of rhododendrons. The spectacular three-acre plot is tended by the Finnerty Garden Friends, a special group of University of Victoria alumni and community members who advise on the planning and development of the year-round garden.

The Gardens were developed when, in 1974, the estate of Mrs. Jeanne Buchanan Simpson of Cowichan Lake was left to the University. She and her husband George, beginning in the 1920's, built up a notable collection of rhododendron species at their Lake Cowichan home. Many plants were grown from seed obtained directly or indirectly from famous plant explorers of the day. Theirs was the largest rhododendron collection in British Columbia.

The Buchanan Simpson's gift transferred to the University the responsibility for the well-being of a significant collection of a popular genus among Victoria gardeners. The University decided to move many of the rhododendrons to the campus where they would form the nucleus of a new garden that was created at the south end of the campus.

The Simpson plants were up to 50 years old and presented a challenge to the transplanters. After the death of her husband, Mrs. Simpson had been unable to maintain the garden properly. The rhododendrons had to struggle for survival without the benefit of summer watering and in competition with the invading "jungle". You will recognize these sometimes distorted giants in the Garden today. Most of them are R. decorum or R. fortunei. In their growth-form they resemble these rhododendron species growing in their native Asian habitats.

The collection now includes more than 200 rhododendron species and azaleas along with an extensive planting of hybrids, most of them of early origin. The accession list includes about 1600 entries for trees and shrubs. All are catalogued and identified by a number that refers to a master list, which is available for veiwing

The rhododendrons may be seen in flower from mid-January until late June, also extensive collections of spectacular perennials from July onwards. Companion plants such as Garrya, Chimonanthus, Hamemalis, Mahonia and Eucryphia extend the season through most of the year.


Leopard's Bane Daisy

Leopard's Bane (Doronicum spp.) is a curious sight in the springtime garden. We tend to think of yellow daisies as a summer and fall plant, and they seem out-of-place among Bergenia, Aquilegia, and late tulips. That being so, they are welcome and cheerful sight when spring days are dull and rainy.

They are not fussy as to soil, just moisture retentive, but well draining, a nice mix of sand and humus suits them fine. Even though they mostly go dormant during the summer, they should not be allowed to dry out, and if planted in light dappled shade that should not be a problem.

They will naturalize in a woodland garden, and several of the named varieties do come true from seed. The rhizomes can be divided in early fall to share or replant. In fact, they improve if divided every four years or so. The blooms also last well when cut for the table.

Flowers come as single or double daisy forms, in various shades of yellow. Dwarf forms, such as 'Gold Dwarf' at only 10 inches tall, tend to bloom earlier in April. Blossoming then progresses through the doubles, such as 'Spring Beauty' and 'Gerhard', to some of the large flowered ones like 'Miss Mason' and 'Harpur Crewe' which bloom into June, and stand to 2 feet tall.

The heart-shaped basal leaves are a nice shade of soft green that contrasts well with dark rhododendron leaves, and if planted among Hostas, Astilbes, or Campanulas, their foliage will fill in spaces for the summer months.

Aren't we so lucky to have so many choices of undemanding plants that can fill gardens with color and beauty, and we hardly have to lift a finger to make them thrive?

Happy planting!

Warren Berg's hybrid Rhododendrons

Some outstanding Rhododendron hybrids were developed by the late Warren Berg, who had a wonderful woodland garden in Pt. Ludlow, Washington. Warren was a plantsman extraordinaire and very much a part of the great Rhododendron hybridizing community in the Pacific Northwest.

Warren was one of the plant hunters who joined trips into Asia, particularly China, just as China re-opened to western plant hunters in the latter part of the 20th century. He often used seed of species he'd collected to grow plants and evaluate their potential both for local garden use and as parents in crosses. He wanted to create good, easy to grow small plants for modern gardens. He also wanted nice foliage displays as well as a range of flower colours.

Warren named his cultivars so people would recognize the hybridizer, and want to collect as many of his cultivars as possible. He often used "bee" in the hybrid name – the "bee" coming from his last name. So, you'll find plants named 'Patty Bee', 'Peter Bee', 'June Bee', 'Honey Bee', etc. There are exceptions, depending on who was being honoured with a cultivar name, hence the plant names 'Ernie Dee; and 'Ginnie Gee'. One of my favourite rhododendrons is 'Golfer', named for Warren's wife Patricia who was an avid golfer. 'Patty Bee' was also named for her.

One of Warren's favourite parents for hybridizing was R. keiskei 'Yaku Fairy', a dwarf, yellow-flowered species from the Japanese island of Yakushima. In addition to providing small plant stature, this species gave him genetic material for his yellow flowers as well as good foliage. And, it was a plant that would cross readily with other species to provide a range of flower colours.

R. 'Wee Bee'

For yellow flowers, look for 'Patty Bee', 'Peter Bee', and 'Golden Bee'. Good pink forms are 'Wee Bee' and 'Too Bee', and forms that are white, or open white flushed with pink include 'Ginnie Gee', 'Ernie Dee', 'June Bee' and 'Wanna Bee'. For one of the most outstanding foliage plants around, you can't beat the aforementioned 'Golfer'. This cultivar has lovely pink flowers, but what I really love is the new foliage that is so covered by indumentum that it appears white. By the end of summer, as the foliage matures, the indumentum is gradually lost, but is replaced with attractive blue-green leaves. They are all "good do-ers" both in the garden or in containers. So, "bee happy" and treat yourself to one of Warren's beautiful creations.

Cinnamon and Nutmeg

The use of cinnamon has been well documented since ancient Egyptian times, but it is actually native to southern China and the Island of Ceylon. Its value, even in ancient times, was such that it has been an important trading commodity from time immemorial. It continues to be one of the most important spices of the world.

Cinnamon is actually the dried inner bark harvested from two trees: Cinnamonum zeylanicum, native to Ceylon and southern India, or C. cassia, from southeast Asia. In the wild, the trees are about 40 to 50 feet tall, but for commercial purposes, trees are grown in plantations where they are severely pruned to be kept just over 6 feet tall. To harvest, twigs are cut from the trees, and the bark is carefully peeled off the twigs to form "quills". The quills are dried by wrapping them around another piece of wood, and during the drying process, the cinnamon ferments slightly. After drying, the quills are unwound and cut to short lengths for sale, or ground into cinnamon powder.

Cinnamon oil can be distilled from the bark, and this is used as a commercial flavoring agent and in the perfume industry. Usually, no reference is made as to which form of cinnamon is sold in a given package, but in North America, the "cassia" form of cinnamon is more commonly available, while Europeans and Mexicans prefer the Ceylonese form of cinnamon. Both forms provide a spice with a rich, aromatic scent and flavor, but the cassia form is thought to have a more robust flavor and the Ceylonese form is more delicate.

Cinnamon is commonly used in baking, in some processed candies and also is often added to pickles. Cassia buds, dried fruit capsules of C. cassia, are also harvested and dried for use in making pickles. The buds have a more pungent flavor of cinnamon.

Nutmeg is the seed of the nutmeg tree, Myristica fragrans. A related spice, mace, is also harvested from the nutmeg seed, but it is the leathery coating that is found wrapped around the actual "nut".

Nutmeg is a medium-sized tree, native to Indonesia. It is now grown throughout southeast Asia and in the West Indies. Nutmeg trees are dioecious, that is, male and female flowers are borne on separate trees. In planting a nutmeg orchard, the grower must ensure there are enough male trees to pollinate the female flowers so about one in every 10 to12 trees will be a male pollinator. Only the female trees bear nuts.

As they ripen, the nut's outer husk splits open, revealing a kernel, wrapped in the mace. After the nuts are gathered the outer husk is removed and the leathery mace is carefully removed by hand. The mace is pressed and dried. The remaining kernel consists of a hard outer shell with the seed inside. These nuts are slowly dried and when curing is complete the hard shell is removed. The kernel within the "nutmeg" is the actual spice and it can be packaged whole or ground. Both nutmeg and mace are used for flavoring sweet dishes, but they are also commonly used to spice meats, fish, preserves, and other food.

Indumentum and Tomentum

Many rhododendrons have felt-like coatings on the top or bottom of the leaves. Composed of small hairs, the coatings can be white, tan, reddish brown or dark brown colored. See photos for illustrative examples.

     R. proteoides      R. 'Sir Charles Lemon'

Indumentum (Latin, literally: "garment") is a coating of hairs on the undersides of a leaf. Tomentum is a coating of hairs on the top surface of leaves. Stems and flowers can also be hairy, and this is generally referred as “tomentose”. A plant surface with any kind of hair is said to be “pubescent”.

Indumentum forms a protective, woolly layer that sheds water and/or provides leaf protection. During cold, dry weather, the hairy indumentum that covers the leaf's underside becomes an insulating shield. Some of the plant hairs hold water and absorb it to provide the plant with moisture in times of drought. During times of heavy rain, the hairs are used by the plant to transpire excess water from the surface of the leaf. Indumentum also provides some protection from insect damage.

Indumentum types include: Hirsute (hairy, shaggy, long-haired), Pilose (long soft hairs), Villous (shaggy), Stellate (radiating in a star-shape), Scabrous (small projections rough to the touch), and Scurfy (very rough to the touch).
