One of the so-called Indian hybrid azaleas, this evergreen shrub bears showy clusters of large single red-purple flowers from early to mid-spring. The broadly funnel-shaped blooms are unscented. The relatively tall rounded plants have elliptic dark green leaves.
Hybrids that have the East Asian species Rhododendron simsii, Rhododendron indicum, and Rhododendron murconatum in their ancestry, Indian Group azaleas were first developed in the nineteenth century for greenhouse...
(Buccaneer Azalea, Evergreen Azalea, Glenn Dale Hybrid Azalea)
Bearing clusters of large dazzling orange-red blooms in late spring, 'Buccaneer' 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, 'Buccaneer' has medium-sized oval leaves that are bronze-tinged when young. The funnel-shaped single flowers are held on strong stems and drop after fading rather than...
(Cadis Azalea, Evergreen Azalea, Gable Hybrid Azalea)
Combining showy bloom and exceptional hardiness, this broadleaf evergreen shrub bears spherical heads of immense soft-pink flowers in late spring. The fragrant ruffled bell-shaped blooms are suffused with pale yellow. The long leathery dark green leaves are red-tinged when young. This cultivar grows relatively rapidly into a rounded medium-sized shrub.
This is one of several rhododendron hybrids developed by Joseph Gable of Stewartstown, Pennsylvania, who is best known as the creator of the...

The funnel-shaped blooms are scentless. The upright, chest-high plants have elliptical, dark glossy-green leaves.
Primarily derived from the East Indian species Rhododendron simsii, Rhododendron indicum, and Rhododendron murconatum, Belgian Indica Hybrid azaleas were originally...

(Calsap Rhododendron, Michener Hybrid Rhododendron, Rhododendron)
As exceptionally hardy as it is beautiful, this hybrid of Rhododendron catawbiense var. album bears spectacular spherical clusters of white flowers with boldly contrasting burgundy-purple blotches. The broadly funnel-shaped blooms appear in late spring. This vigorous evergreen forms a rounded head-high shrub with long, elliptic, yellow-green leaves.
Like most rhododendrons, 'Calsap' prefers some shade and a highly organic acid soil that is evenly moist but well-drained. It makes...
One of the horticultural dynasties of nineteenth and twentieth century England, the Waterer family introduced a diversity of large-leaved rhododendrons through their Knap Hill and Bagshot nurseries. Many are hybrids of hardy species including R. catawbiense, R. maximum, and R. ponticum. Their wide-flaring funnel-shaped flowers are borne in large rounded trusses in spring. The red, pink, purple, or white blooms often have a contrasting blotch...
(Caroline Gable Azalea, Evergreen Azalea, Gable Hybrid Azalea)
Combining showy bloom and superior cold hardiness, 'Caroline Gable' bears glowing purple-pink flowers from mid- to late spring on vigorous upright plants. The hose-in-hose flowers (two "stacked" whorls of petals) have a rose blotch. The small oval glossy-green leaves take on coppery tints in fall.
Developed mostly by Joseph Gable of Stewartstown, Pennsylvania, Gable Hybrids include some of the hardiest evergreen azaleas available, thanks to the contributions of Rhododendron yedoense...
(Carla Hybrid Azalea, Carror Azalea, Evergreen Azalea)
The cheerful blooms of 'Carror' are large, semi-double and rich rosy pink.
The Carla azaleas were developed at an azalea breeding program at North Carolina State University. The complex hybrids were bred for disease-resistant and cold hardiness.
This medium-sized evergreen to semi-evergreen shrub is grown for its showy spring blooms. It has dark green, hairy leaves and its flowers are funnel-shaped with ruffled edges. The flower buds develop in summer for the following spring’s display,...
