Bright pink flowers cover this compact upright evergreen azalea in mid-spring. The unscented flowers of 'Tradition' are hose-in-hose (two "stacked" whorls of petals). The oval glossy dark green leaves take on coppery tints in winter. This cultivar slowly forms a rounded, chest-high shrub.
The Kurume Hybrids result from some 300 years of hybridizing in Japan. Their ancestry likely includes Rhododendron kaempferi, R. kiusianum, and other Japanese species and hybrids....

(Evergreen Azalea, Glenn Dale Hybrid Azalea, Treasure Hybrid Azalea)
Displaying showy clusters of large, single, faintly pink-tinged white blooms in early to mid-spring, 'Treasure' 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, upright and spreading shrub, this vigorous cultivar has medium-sized oval leaves. The flowers are held on strong stems and drop after fading rather...
Comprising more than 400 cultivars, the Glenn Dale hybrid azaleas were developed from the late 1920s through the 1940s at the United States Department of Agriculture’s Plant Introduction Station at Glenn Dale, Maryland. This breeding program was initiated by Benjamin Y. Morrison, the first director of the United States National Arboretum. These relatively cold-hardy evergreen azaleas are complex hybrids involving many Asian and North American rhododendrons.
These small to medium-sized shrubs...
(Evergreen Azalea, Glenn Dale Azalea, Trouper Azalea)
Bearing showy clusters of large brilliant scarlet blooms in late spring, 'Trouper' is one of 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 a chest-high, rounded shrub, 'Trouper' has fuzzy dark green oval leaves, some of which may be shed in severe winters. The funnel-shaped single flowers are held on strong stems and drop after fading...
(Rhododendron, Venetian Chimes Rhododendron)
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...
(Evergreen Azalea, Veronica Azalea)
A Belgian Indica Hybrid, this evergreen azalea bears showy clusters of large double purplish-pink flowers in late winter and early spring. It may bloom from late fall to spring in frost-free areas. The mounded waist-high plants have elliptic dark glossy-green leaves.
Primarily derived from the East Indian species Rhododendron simsii, Rhododendron indicum, and Rhododendron murconatum, Belgian Indica Hybrid azaleas were originally developed for greenhouse forcing but...
Auburn University Horticulture Department, Auburn, AL
An dense upright waist-high shrub that bears showy few-flowered clusters of large single white flowers with rose-red rims, this is one of a number of evergreen azaleas introduced by James Harris of Lawrenceville, Georgia, in the 1970s and 1980s. The wide-flaring funnel-shaped blooms appear in spring. The small, hairy, elliptic, mid-green leaves assume coppery hues in cold weather.
Harris azaleas prefer partial shade and highly organic acid soil that is evenly moist but well-drained. Plant...
The deciduous Knap Hill hybrid azaleas were originally developed by Anthony Waterer at the famed Knap Hill Nursery in England around 1860. The complex hybrids were bred with species from the United States and China. They are noted for usually fragrant, large, mid or late season blooms in a wide range of colors. The plants are medium to tall in height, very hardy, vigorous in growth and easily propagated.
Deciduous azaleas generally have upright, rounded habits. The leaves are dark green and...
The clustered fragrant creamy white flowers of this Mollis Azalea open from pale yellow buds in late spring, before the foliage has fully emerged. The large funnel-shaped blooms bear a yellow blotch. This upright open deciduous shrub has elliptical leaves that color nicely in fall. It is extremely cold-hardy.
Developed in the late nineteenth and early twentienth centuries, Mollis Azaleas include Rhododendron molle and R. japonicum in their pedigree.
