Fragrant Rhododendron fortunei

Plant hunter Robert Fortune discovered this lovely species in 1855. It is a fragrant rhododendron...but unlike those sweetly scented, tender beauties lindleyi, nuttallii and maddenii, R. fortunei is quite hardy.

Fortune's original collections were made in Chekiang Province, in eastern China, at about 3,000 feet. Other plant hunters later found the species in Anhwei, Kiangsi, and Hunan Provinces growing in woods and forests at 2,000-4,000 feet in elevation. Plant hunter Robert Wilson noted that the species was common on other Chekiang mountains, particularly in the Lu Shan range of the neighboring province of Kiangsi, to the west.

The leaves of R. fortunei are handsome, and show some variation. They are 3 to 7 inches long, 1.5 to 3 inches wide. A prominent and very attractive feature is the deep red of the midrib and petioles (leaf stems); these create a ring of color around the dormant bud that seems to deepen and become more conspicuous in winter. The leaves of the Lu Shan form are typically a dull, olive green in color, and have rich red petioles.

The flowers of R. fortunei are borne in a loose truss of 5 to 12, and are shaped like wide bells...funnel-campanulate. They are pink to pale pinkish-lilac or rose and are fragrant.

R. fortunei has been much used for hybridizing, particularly in North America, and especially in the East...where it is appreciated for its tolerance of summer heat and winter cold. The two great hybridizers, Rothschild and Dexter, made free use of it this rhododendron as a parent. Indeed, one of the most loved hybrids of all time in eastern North America is Dexter's R. 'Scintillation'.

It is noteworthy that a particularly fine large flowered, sweet-scented R. fortunei clone was used as the seed parent of the original 'Loderi' hybrid grex. The other parent is R. griffithianum; a tender rhododendron found growing in the lower elevations of the Himalayas.

"A" is for Rhododendron albrechtii

I keep a wish list of rhododendrons I want, and at the moment, the species R. albrechtii is included in the top three of my list.  I grew it in my old garden, but sadly, when I moved, it was one of the plants I had to leave behind.  I haven't found a replacement plant for sale yet, but I keep looking, and after all, the hunt is almost as much fun as growing the plant.  I may have to break down and order some seed of this species as it's not commonly available in the trade as established plants.

Why do I like it so much?  Well, in bloom it's such a sweetheart!  The plant I grew had deep cerise-pink flowers, two or three to a cluster, and each flower was almost 2 inches across in size.  In doing a bit of internet searching, I see other growers report floral colours ranging from the deep rosy pinks into the purple reds, and up to 5 flowers per cluster.  In the Pacific Northwest, R. albrechtii usually blooms in mid to late April.

The plant, native to Japan, is a deciduous azalea, and the leaves on my "old" plant turned a lovely yellow before they dropped in the fall.  I'm not sure if fall leaf colour is a constant for all albrechtii plants, but it's nice when it happens.  I had my plant situated on the north side of the house, but it got good light from mid-afternoon on into the evening.  It prefers areas with cooler summer temperatures, so avoid planting sites that receive hot temperatures and mid-day sun.  The usual recommendation of even soil moisture applies.  Plants grow to a height of about 4 feet, so R. albrechtii is a good choice for the small garden, or even a large container.  It's also a good choice for woodland plantings. Do keep an eye out for this great little plant – it should be on everyone's wish list.
