Bearing showy clusters of large, purple-red, maroon-blotched flowers in spring, 'Afterglow' is one of the more than 400 evergreen azalea hybrids developed from the late 1920s through the 1940s at the United States Department of Agriculture’s Plant Introduction Station at Glenn Dale, Maryland.
Eventually forming an eye-high shrub, this dense upright cultivar has rounded mid-green leaves that go burgundy in fall. The funnel-shaped flowers are held on strong stems and drop after fading rather...
(Alaska Hybrid Azalea, Hybrid Azalea, Rutherford Hybrid Azalea)
One of the Rutherford Hybrid azaleas, this evergreen shrub bears showy clusters of ruffled white flowers from early to mid-spring. It may also bloom in fall and winter in frost-free climates. The single or double, funnel-shaped blooms have a yellow-green blotch on their upper lobes. The compact mounded plants have elliptic dark green leaves.
Tracing their ancestry to the Kurume Hybrids as well as to several East Asian species including Rhododendron simsii, R. indicum,...
(Amelia Rose Azalea, Evergreen Azalea)
One of more than 30 evergreen azaleas developed and named by Gene and Jane Aromi of Mobile, Alabama, 'Amelia Rose' bears showy clusters of large deep purple-red double flowers in early to mid-spring. The flowers are hose-in-hose (with "stacked" whorls of petals) and have a dark red eye blotch. This dense rounded head-high shrub has medium-sized elliptic dark-green leaves.
This azalea prefers partial shade and highly organic acid soil that is evenly moist but well drained. Plant it shallowly and...
(America Rhododendron, Rhododendron)
Introduced in the early twentieth century and still valued for its exceptional hardiness and showy flowers, this hybrid rhododendron bears compact spherical trusses of blue-tinged red flowers in late spring. The funnel-shaped blooms have a dark red blotch. The long leaves are a dull medium-green. This cultivar eventually forms a large loose sprawling shrub that becomes sparser and laxer with increasing shade.
Although most rhododendrons prefer partial shade and highly organic acid soil that...
(Amoenum Azalea, Evergreen Azalea)
Introduced to the West from Japan in 1845, this close relative of the Kurume azaleas bears vivid magenta-purple flowers in mid-spring.
The semi-double blooms are hose-in-hose (with two "stacked" whorls of petals). The small oval semi-evergreen leaves are glossy dark green. This rather slow-growing cultivar can eventually form a large shrub.
As with the Kurume Hybrids, 'Amoenum' has Rhododendron kaempferi, R. kiusianum, and other Japanese species in its ancestry....
(Amy Cotta Rhododendron, Rhododendron)
A dwarf mutation of the famous hybrid rhododendron 'PJM', ‘Amy Cotta’ grows slowly to form a dense symmetrical evergreen shrub. Clusters of small, lavender-pink, funnel-shaped flowers envelop the compact mounded plants in early spring. The small, oval, shiny dark green leaves turn burgundy and purple in winter. They emit a spicy fragrance when bruised.
This cultivar prefers light shade and highly organic, acid soil that is evenly moist but well-drained. It does well in full sun in cooler climates....

(Amy Azalea, Evergreen Azalea)
An evergreen azalea with close ties to the Kurume Hybrids, 'Amy' bears large soft pink flowers with red-speckled upper lobes from early to mid-spring.
The semi-double blooms are hose-in-hose (with two "stacked" whorls of petals). The small oval leaves are glossy dark green. This cultivar slowly forms a dense rounded shoulder-high shrub.
Azaleas prefer partial shade and highly organic acid soil that is evenly moist but well-drained. Plant them shallowly and mulch well to conserve moisture...
(Anah Kruschke Rhododendron, Rhododendron)
A hybrid of Rhododendron ponticum, 'Anah Kruschke' is a beautiful rounded evergreen shrub which is densely clothed in large shiny dark green foliage. Masses of deep reddish-purple flowers appear in ball-shaped clusters (trusses) from mid- to late-spring. The funnel-shaped blooms have a burgundy blotch.
Although most rhododendrons prefer partial shade and highly organic acid soil that is evenly moist but well-drained, ‘Anah Kruschkle’ does well in considerable sun. Plant rhododendrons...
(Ann Bedford Rhododendron, Rhododendron)
The hybrid rhododendron 'Ann Bedford' bears rounded clusters of purple flowers in spring. This evergreen shrub has large elliptic dark green leaves.
Like most rhododendrons, 'Ann Bedford' favors chilly winters, moderate summers, and well-drained, humus-rich, acid soil. Plant it shallowly and mulch well to conserve moisture and suppress weeds. Do any necessary pruning directly after the flowers fade, before new flower buds form. Try to site it where it has room to grow to full size.
Vigorous and fast-growing, this large hybrid rhododendron bears imposing spherical clusters of immense rose-pink blooms from mid- to late spring. The wide-flaring, funnel-shaped blooms have brown-spotted upper lobes. This broad-spreading shrub has long elliptic olive-green leaves.
Like most rhododendrons, 'Anna Rose Whitney' does well in partial shade and highly organic, well-drained, acid soil. It departs from the norm, however, in tolerating full sun. Plant it shallowly and mulch well to...
