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...

(Evergreen Azalea)

Showy clusters of large glowing rose-red flowers adorn the branches of this evergreen hybrid azalea in mid-spring. The broadly funnel shaped blooms have slightly ruffled petals. This cultivar slowly forms a compact rounded plant clad in small oval dark green leaves. The leaves turn reddish in fall.

Azaleas prefer sites with partial shade and highly organic acid soil that is evenly moist but well-drained. Plant them shallowly and mulch well to conserve moisture and suppress weeds. They prefer...

(Caronella Rhododendron)

One of the shrimp-pink hybrid rhododendrons from the famed Weston Nurseries in Massachusetts, ‘Caronella’ is semi-deciduous, vigorous, upright in form and fast growing. The flowers are light pink with purple-pink markings which produce a striped effect. They are also marked with a yellow blotch. The foliage exhibits some fall color in shades of red, yellow and orange.

The beautiful, rounded shrubs are densely clothed in dark green, shiny foliage. The long leaves are elliptical, held alternately...

(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,...

(Cascade Azalea, Evergreen Azalea, Morrison Hybrid Azalea)

Bearing showy clusters of white, pink-flecked, semi-double blooms in early spring, 'Cascade' 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 flaring funnel-shaped blooms are hose-in-hose (with two "stacked" whorls of petals). They drop after fading rather than persisting on the plant. This broadly upright, chest-high shrub has rounded medium-...

(Evergreen Azalea)

Bearing showy clusters of white, lavender-streaked flowers in mid- to late spring, 'Cavatina' 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 a shoulder-high shrub, this broadly upright cultivar has rounded medium- to dark-green leaves. The broadly funnel-shaped single flowers are held on strong stems and drop after fading...

(Cheerful Giant Azalea, Deciduous Azalea)

Showy spherical clusters of large double pale yellow flowers crowd the upright branches of this deciduous azalea in late spring, before the foliage has fully emerged. The frilly-edged blooms have an apricot-orange blotch and peachy segment tips. This stout-branched shoulder-high shrub has elliptical medium-green leaves that are coppery when young and red-tinged in fall.

This is a descendant of hybrids developed in the late nineteenth and early twentienth centuries at the famed Knap Hill Nursery...

(Evergreen Azalea)

Showy clusters of large deep rose-pink flowers adorn the branches of this evergreen hybrid azalea in spring. The broadly funnel shaped blooms have slightly ruffled petals. This cultivar slowly forms a compact rounded plant clad in small oval leaves.

Azaleas prefer sites with partial shade and highly organic acid soil that is evenly moist but well-drained. Plant them shallowly and mulch well to conserve moisture and suppress weeds. They prefer warm summers and cool winters and require some...

(Deciduous 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 cultivar 'Clearcreek' bears showy domed clusters of large funnel-shaped pale yellow flowers in mid-spring. A dark yellow blotch adorns their upper petals. The upright medium-sized plants have lance-shaped light green leaves. Aromi azaleas prefer partial shade and highly organic acid soil that is...
