(Deciduous Azalea, Ghent Azalea, Pallas Azalea)
The enormous genus Rhododendron comprises more than a thousand species. They are naturally distributed on every continent except Antarctica, Africa and South America. The highest concentrations of species occur in the temperate and mountainous regions of China, Japan, Korea and Taiwan. Grown for their showy flowers, rhododendrons are garden favorites worldwide and have been highly hybridized. There are more than 28,000 registered cultivars.
Plants in this genus are extremely variable...
The evergreen azalea ‘Pandora' bears light pink, funnel-shaped blooms in spring. It forms an upright, medium-sized shrub with oval green leaves.
This cultivar is part of a group of hybrids developed by Julian J. Chisolm in the late 1940s and later released by Dr. E. I. Merritt. Most include the hardy East Asian azalea Rhododendron yedoense variety poukhanense in their ancestry.
Azaleas prefer partial shade and highly organic acid soil that is evenly moist but well-drained....
(Deciduous Azalea, Parade Azalea)
Noteworthy for its showy fragrant flowers, its late season of bloom, and its colorful fall foliage, this tall upright deciduous shrub is one of many hybrid azaleas introduced by Weston Nurseries of Hopkinton, Massachusetts. A hybrid of the eastern North American native Rhododendron viscosum, it bears showy heads of single deep pink blooms in early summer. The wide-flaring funnel-shaped blooms have an orange blotch on their upper lobes. The oval, mid-green, mildew-resistant leaves turn bronze...

(Deciduous Azalea, Peachy Keen Azalea)
Dense clusters of ruffled, peach-pink, funnel-shaped flowers envelop this deciduous azalea in late spring, before the foliage has fully emerged. Each bloom bears a lemon-yellow blotch on its upper petal. This compact rounded shrub has hairy elliptic leaves that color nicely in fall. It is one of many azaleas resulting from the hybridizing work of Edgar Stead of Christchurch, New Zealand, using Knap Hill Hybrids and other azalea hybrids and species.
Azaleas prefer sites with partial shade and...
Bearing showy clusters of large rose-pink flowers in mid-spring, 'Pearl Bradford' 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. The broadly funnel shaped flowers have red-flecked throats.
Growing slowly into a low mounded shrub, this densely branched cultivar has oval shiny dark green leaves. The flowers are held on strong stems and drop...
(Evergreen Azalea, Indian Hybrid Azalea, Perfection Azalea)
One of the so-called Indian Hybrid azaleas, this evergreen shrub bears showy clusters of large pink funnel-shaped flowers. The unscented blooms appear from late winter into spring, but may also bloom from late fall through winter in frost-free districts. The compact mounded plants have elliptic dark green leaves.
Hybrids derived from several East Asian species including Rhododendron simsii, R. indicum, and R. murconatum, Indian Hybrid azaleas were...

(Deciduous Azalea, Knap Hill Hybrid Azalea, Persil Deciduous Azalea)
Abundant clusters of large white funnel-shaped blooms ornament this Knap Hill Hybrid azalea in late spring, before the foliage has fully emerged. Each flower bears a golden-yellow blotch. This large upright shrub has medium-green elliptical leaves that color nicely in fall.
Developed in the late nineteenth and early twentieth centuries at the famed Knap Hill Nursery in England, Knap Hill Hybrids are deciduous azaleas whose ancestry includes the Ghent and Molle hybrids and several Japanese...
(Evergreen Azalea, Phoenicia Azalea, Southern Indica Hybrid Azalea)
Southern Indica or sun azaleas are a terrific group of broadleaf evergreens with a hearty tolerance of heat and sunlight. Taller than most other evergreen azaleas, they form handsome broadly mounded bushes with rounded dark green leaves. Late winter and spring find them enveloped in showy clusters of large white, pink, red, or purple flowers. The funnel-shaped blooms often have a contrasting blotch. Although most cultivars bear single flowers, double- and semi-double-flowered selections are also...

(Aromi Hybrid Azalea, Deciduous Azalea, Pink Carousel Azalea)
Bred in Mobile, Alabama, the Aromi deciduous azaleas result from crosses between Southeast United States natives (primarily Rhododendron austrinum) and hybrid azaleas such as the Exburys. The showy pink funnel-shaped flowers of the cultivar 'Pink Carousel' open from scarlet buds in mid-spring. The clustered blooms bear a gold blotch on their upper petals. The upright medium-sized plants have lance-shaped light green leaves.
Aromi azaleas prefer partial shade and highly organic acid soil...
