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...
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-...
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...
