20103 Rhododendron fletcheranum — (RN, rn, Maddenia) 30", 5°F, E-M, 4/4. While this variety is a member of the Maddenii series, it is not tender like most. It may even deserve a hardier rating than 5o F. Under snow it survived the -12o F. experienced here in 1972. The foliage is bristly and hairy as are the branches. The leaves are 1" to 2" long and 1" across, turning deep attractive bronze in winter. The flowers are showy bright lemon yellow. Though rare, it is probably one of the most outstanding of the yellow rhododendrons. 10-15"

The fragrant flowers are white with a light kiss of pink. The name means "willow leaved" because of its linear leaves. Vigorous grower. 21-30"

Rhododendron fortunei — (HY, hy, Fortunea) Here is hardiness and beauty all in one plant. Growth habit is open, upright and treelike. Large leaves, large fragrant flowers and exceptional hardiness help make R. fortunei one of the most distinguished flowering evergreen shrub that can be grown in the northeastern United States. Quoting from David Leach’s Rhododendrons of the World, "Unquestionably this is among the finest few of rhododendron species."

20312 Rhododendron fortunei ssp. fortunei — 6', -15°F, M, 4/4. The deliciously fragrant flowers are often more than 4" in diameter and are a blush pink, fading to white. The enormous, scented blossoms, exquisitely modeled, form a tumbling cascade of magnificence which can scarcely be matched in the genus. In addition to its remarkable floral effect, it is exceptionally vigorous, free from pests and attractive in foliage and habit. 6-10", 10-15", 15-21", 21-30", 30-36"

20034 Rhododendron fulvum — (HY, hy, Fulva) 4', 0°F, EM, 3/5. Growth habit is open, upright, treelike, with spectacular foliage. Leaves, up to 10" long, are obovate and smooth shiny dark green on the top side. The fawn to bright cinnamon underside is the most fabulous indumentum of any rhododendron. Flowers, to 2" long are open funnel shaped, white blushed rose to deep rose, occasionally blotched and spotted crimson and are held in great loose rounded trusses of up to 20. This is a special species, not seen in many gardens. 15-21"

20421 Rhododendron glaucophyllum — (RN, rn, Glauca). 3', 5°F, EM. This fragrant species with lanceolate leaves waxy and densely scaled beneath. Brown bark peels.

20120 Rhododendron griersonianum — (HY, hy, Griersoniana) 3', 10°F, L, 3/3. This is the species that has produced so many great hybrids. The flowers are a scarlet red quite unlike any other species of rhododendron. Narrow leaves are a mat green above with loose woolly tomentum below. 21-30"

20159 Rhododendron hippophaeoides var. hippophaeoides — (RN, rn, Lapponica) 3', -25°F, E, 4/2-3. The best, hardiest plant of the species, this variety withstands frost even when in flower. It is also tolerant of sun and swampy conditions. The beautiful lavender-blue flowers occur in clusters of 6-8. Beautiful!

Rhododendron hirsutum — (RN, rn, Rhododendron) . 1', -15°F, L-VL, 2/3. Growth habit is twiggy, spreading, and open. Small leaves are dark green. Tubular flowers, ¾" long, held in loose clusters of 5-8, are white, rosy pink, or nearly scarlet.

20195 Rhododendron hunnewellianum — (HY, hy, Argyrophylla) 5', 5°F, VE-EM, 2-3/3. This shrub becomes a small tree at maturity. It has medium to large, very narrow oblong leaves glabrous above and covered with dense white or gray hairs on the undersides. The 2" flowers bloom 5-8 to a truss and are white, tinged pink, spotted inside with pink. 10-15", 15-21"

0132 Rhododendron hyperythrum — (HY, hy, Pontica) 5', -15°F, EM, 3/4. Another of the hardy ponticums. R. hyperythrum has long narrow curled leaves that are of the utmost interest. Well worthy of growing for its foliage alone. It has lovely white flowers that burst open from pink buds. A desirable plant. 10-15"

20134 Rhododendron impeditum — (RN, rn, Lapponica) 1', -15°F, EM, 4/4. One of the best dwarf rhododendrons, this species has a tight compact habit with attractive silver-gray foliage. Bright blue-purple flowers make a nice contrast. David G. Leach, in Rhododendrons of the World, suggests an excellent use for it: "This is an ideal species for the rock garden, in the forefront of a shrub border or as an edging for beds. Planted about 15" apart, a number of plants will grow together to form an impenetrable ground cover, handsome at all seasons and especially effective when such an expanse becomes a blanket of blue flowers. 6-10"

20064 Rhododendron insigne — (HY, hy, Argyrophylla) 3', 0°F, ML, 4/5. This slow growing plant fully lives up to its name: remarkable. The leaves, to 5" long, oblong lanceolate in shape, are dark glossy green above, and show a skin like tawny indumentum with a lovely coppery sheen on the undersides. Bell shaped flowers, to 2" long, in trusses to 8, are pinkish white with crimson spotting and external rosy pink stripes. Beautiful! 10-15"

Rhododendron irroratum — (HY, hy, Irrorata) 5', 0°F, E-EM, 3-4/3-4. The habit of this plant is somewhat treelike and leggy. Pale green, smooth 5" leaves are paler and nearly hairless underneath. Tubular, 2" bell-shaped flowers are white to creamy yellow, suffused with pink or, usually heavily spotted with crimson or green, and are held in trusses of up to 15.

20441 Rhododendron johnstoneanum - Double form — (RN, rn, Maddenia) 4', 15°F, E-M, 4/3/3-4. Medium sized leaves are elliptic or obovate-elliptic, fringed with distinctive hairs along edge when young, glabrous, the underside with dense layer of scales. Fragrant flowers, to 3" long, are funnel-bell-shaped, with nice substance, in loose clusters of 4 blooms. They are creamy white to pale yellow, perhaps yellow blotched, occasionally red spotted. This will produce both single and double flowers, producing more single flowers as a young plant. 10-15", 21-30"

20150 Rhododendron kiusianum — (TT,tu) 2', -10°F, M-ML, 5/5. One of the best of the native Japanese azalea species. Buds young and heavily, making a solid mass of flowers. Terrific habit for bonsai or just for planting in your garden. You must have this for the sheer joy of it.

20443 Rhododendron kyawii — (HY, hy, Parishia) 5', 5°F, E, 4-5/3. Bright crimson scarlet. An exceptionally beautiful and showy flower. Good foliage. The Rhododendron Handbook states that it flowers in June, however, this form flowers in April. It fits the original description in The Species of Rhododendron except that the under surface of the leaf does not seem to have as much indumentum. It appears that information on this species is incomplete and I quote from The Species Rhododendron: ‘This has been collected only once and the material (to describe from) is scanty.’

20170 Rhododendron lacteum — (Hy, hy, Talenesia) 5', -5°F, EM, 4-5/3-4. One of the most sought after species in the genus Rhododendron. Its huge trusses of yellow make it famous for having the finest flowers of its genus. The handsome foliage is large, to 8" long, oval, and strongly decorative in nature, being covered with a fawn colored felt-like indumentum underneath. It makes a magnificent bold looking plant and is one rhododendron that does better grafted than on its own roots. Flowers to 2" long, are wide funnel form, the pale yellow or sulphur white color occasionally tinged with pink or with a crimson blotch, sometimes flowering when quite young. 6-10"

20095 Rhododendron lanigerum — (HY, hy, Arborea) 4', 5°F, E-EM, 3-4/3. Large bell shaped deep pink flowers occur in tight trusses above long interestingly veined leaves. 15-21"

20187 Rhododendron leucapsis — (RN, rn, Boothia) 2', 5°F, E, 3-4/3-4. Habit is upright and open on this bushy little undershrub, and the new growth is very hairy and scaly. Dark, glossy green leaves enhance flowers, up to 2" across, which are open flat and round, held in trusses of 2-3. One of the most attractive features of this particular plant is the contrast of the chocolate brown anthers against the pure white background of the flower, which often has a kiss of pink on the backside of the petals. 3-6"

20229 Rhododendron longesquamatum — (Hy, hy, Maculifera) 4', -15°F, M, 2/3. Compact growth habit, with large oblong leaves that are hairy when young and dark green, shiny and smooth later. The underside is paler, only slightly as shiny, and thinly dotted with glands. In trusses of 6-12, soft pink or rose flowers, blotched with crimson are bell- shaped. 10-15", 15-21"

20314 Rhododendron lutescens — (RN, rn, Triflora) 6', 5°F, EM, 4/3. Sunny yellow flowers bloom amidst bronzy red foliage. Open and upright, the new growth is bright red, and creates quite a display in itself. The medium sized leaves, which range in color from dull dark green to a lovely bronzy red, are oblong or lance shaped. Very sun tolerant. 6-10", 15-21", 21-30"

20102 Rhododendron luteum — (PE, pe, Pentanthera) 4', -15°F, M-L, 3-4/3. A deciduous shrub with an open, upright habit. The oblong leaves to 5" long are sparsely covered on both sides with stiff, flat hairs. The delightful, fragrant, 2" yellow flowers open before the leaves. These tubular-shaped blooms are extremely sticky on the outside and are carried in trusses of up to 12 blooms. Very, very nice. 10-15"
