Rhododendron of the Year Awards, 2008
Ray Smith
ARS Plant Awards Committee Co-chair
Glenwood, Maryland

        The ARS Plant Awards Committee has selected the Rhododendron of the Year awards for 2008. Because of climate differences, the committee selected plants for seven regions: an elepidote, a lepidote, a deciduous azalea and an evergreen azalea. The Vireya/Swisher Award is given to a vireya rhododendron.
        The first criterion was that the plant perform well in the region, even for a novice. That plant had to exhibit good form, foliage and flowers, to prove itself cold and heat hardy for the region, and to show resistance to pests and diseases. In addition, the plant had to be available in the nursery trade and the name registered with the ARS.

Northeastern Region
'Capistrano': Elepidote ('Hindustan' (s) X {[(R. catawbiense, white-flowered x (R. fortunei ssp. discolor x Fabia Group)] x ('Russell Harmon' x 'Goldsworth Orange')} x 'Golden Gala'). Thought by many to be the best hardy yellow elepidote in general distribution; has a full, dome-shaped, pale greenish yellow truss in late-midseason; a mounded plant with lush, deep green leaves, growing more wide than tall; to 5' in ten years and hardy to -15F; Leach hybrid.

'Landmark': Lepidote ('Counterpoint' X Carolina Rose Group). Seen from afar, this is the elusive red lepidote; closer observation shows the compact trusses of wavy-edged flowers to be purplish-red; an upright grower (4' in ten years), covered with flowers in the early spring and excellent bronze-purple color in winter; hardy to -20F and very sun-tolerant; another great Mezitt hybrid.

R. atlanticum: Deciduous Azalea. The coast azalea, native to the coastal plain of the eastern United States from Delaware to Georgia; midseason bloom with very fragrant white flowers, often flushed with pink or purple; stoloniferous, sending out shoots underground to form new plants; a mounding plant with distinctive bluish-green foliage, growing to 3-4' in ten years, hardy to -15F.

'Linda Stuart': Evergreen Azalea ('Blaauw's Pink' X unknown seedling). A striking hose-in-hose picotee flower on an upright growing plant; cream center edged with salmon-pink; 4-5' tall in ten years, hardy to -15F; will take hot summers and cold winters; a Leon Yavorsky hybrid.

Mid Atlantic Region
'Mist Maiden': Elepidote (selection from R. yakushimanum). Large apple blossom pink flowers emerge from deep-pink buds and fade to a snowy white; a very hardy (-25F) plant, and deer resistant due to the thick brown indumentum on the underside of the dark green foliage; introduced by David Leach, who felt it was a pure yak; most observers, however, feel it is a hybrid, probably a yak smirnowii cross.

'Weston's Aglo': Lepidote (R. minus, compact selection X pink-flowered R. dauricum hybrid). Sister seedling of 'Olga Mezitt,' sharing many fine qualities with its sibling; early blooming and sun-tolerant, having light pink flowers with a reddish throat; glossy foliage turns bronze in winter; very hardy (-25F) and compact plant, growing to 4-6' in 10 years; a Mezitt hybrid.

'White Lightning': Deciduous Azalea (natural R. arborescens hybrid). A natural hybrid found growing in the wild near Franklin, North Carolina, by Clarence Towe; very fragrant, large white flowers with a yellow blotch in early to midsummer; dark green foliage on a dense and compact plant, reaching 4' tall in ten years.

'Dream': Evergreen Azalea (R. simsii X R. mucronatum). Large wavy-edged blooms (up to 3 across) of a strong purple-pink color, blotched with darker spots; early season bloomer with a spreading growth habit up to 6' tall; hardy to -5 or -10F; a Glenn Dale Hybrid by Ben Morrison.

Southeastern Region
'Vivacious': Elepidote ('America' X 'Doctor Ross'). Has exceptional color and superb foliage; strong bright red, wavy-edged blooms in ball-shaped trusses of ten or more flowers; a late midseason bloomer that is hardy to -10 F and grows broader than tall, to 3' by 4' wide in ten years; a Forster hybrid from Vineland Station Horticultural Research Institute of Ontario.

'Olga Mezitt': Lepidote (R. minus, compact selection X pink-flowered R. dauricum hybrid). In spring, the plant is transformed by small tight balls of clear pink covering every limb; blooms early, a little later than the PJM Group, often avoiding that late frost; in fall, the bright light green summer leaves turn a beautiful mahogany adding great color to the winter garden; an upright grower, reaching 5-6' in ten years; hardy to -15F and sun tolerant - especially valuable in gardens without much shade; a Mezitt hybrid.

R. austrinum: Deciduous Azalea. Known variously as the Flame Azalea, Florida Azalea, or the Florida Flame Azalea; native to the Florida panhandle and nearby areas of Georgia, Alabama and Mississippi; very fragrant blooms in shades of yellow, gold, and orange in the early spring, about the same time as the leaves appear; has an open growth habit and is one of the easiest of the native azaleas to grow; reaches 10' in the wild, but will often remain smaller in the garden, with a spread about half its height; hardy to -15 F, yet the most heat tolerant of the native azaleas; this heat tolerance makes it valuable for hybridizers and it is often crossed with other deciduous azaleas to increase their heat tolerance.

'Elsie Lee': Evergreen Azalea ('Desiree' X 'Rosebud'). A tall, upright grower that can be quite open in shade; hardy to -15 F; the late midseason bloomer has 2-3, semi-double, frilly bluish-lavender flowers; a great plant, hardy and showy, and an exceptional parent in hybridizing; a Shammarello hybrid.
