(Carla Hybrid Azalea)

Bred to grow vigorously and bloom heavily in the heat, humidity, and drought of the Southeast United States, these evergreen azaleas were developed from 1960 onward at North Carolina State and Louisiana State universities using Kurume, Kaempferi, Belgian Indica, and Satsuki hybrids. Their broadly funnel-shaped single, semi-double, or double blooms are usually red, orange, or pink, often with a contrasting blotch. The dense, rounded, typically compact plants have small elliptic medium- to dark-green...

(Carolinianum Rhododendron)

A parent of many well-known cultivars (including the PJM hybrids), these small to medium-sized rhododendrons are outstanding ornamental plants in their own right. They are selections of a distinct race of Rhododendron minus var. minus from the the mountains of western North Carolina. These evergreen shrubs bear rounded trusses of rosy purple, pink, or white flowers from early to mid-spring. The wide-flaring funnel-shaped blooms often have a contrasting greenish-yellow blotch on...

(Chisolm-Merritt Hybrid Azalea)

Bearing pink or red flowers in early to mid-spring, these hybrids were developed by Julian J. Chisolm in the 1930s and were later released by Dr. E. I. Merritt. Most include the hardy East Asian azalea Rhododendron yedoense variety poukhanense as a parent. The result is a group of hardy, compact, broad-spreading hybrids with oval, dark green, hairy leaves and clusters of showy flowers. Many bear hose-in-hose blooms (with two "stacked" whorls of petals). The broadly funnel-shaped...

(Dexter Rhododendron)

Developed in the 1920s and 1930s by Charles O. Dexter of Massachusetts, these large hardy evergreen rhododendrons have several Asian and American species in their lineage, including R. fortunei and R. catawbiense . Dexter Hybrids typically bear generous rounded trusses of large, often fragrant, funnel-shaped flowers in mid- or late spring. The blooms may be white, pink, red, purple, lavender, or creamy yellow. The blooms often bear prominent blotches or speckles....

(Endtz & Co Hybrid Rhododendron)

L. J. Endtz of Boskoop, Holland, developed a number of rhododendron hybrids in the early twentieth century that are still widely planted today. 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 on their upper lobes. The upright rounded plants have large leathery leaves that are often glossy dark green. Among the best-known Endtz Hybrids are 'Antoon van Welie', 'Doctor Arnold W. Endtz', 'Louis...

(Exbury Hybrid Azalea)

Noted for their bright flowers and considerable cold-hardiness, these deciduous azaleas were developed by Lionel de Rothschild at his Exbury Estate in England. Their pedigree includes the Ghent and Molle hybrids and numerous Japanese and American native azaleas. The large funnel-shaped blooms are often fragrant or ruffled and come in a wide range of colors including white, yellow, red, orange and pink. They cluster near the ends of the branches in mid- to late spring, usually before the foliage emerges....

(Gable Hybrid Azalea)

Developed mostly by Joseph Gable of Stewartstown, Pennsylvania, these hybrid evergreen azaleas include some of the hardiest available, thanks to the contributions of Rhododendron yedoense var. poukhanense and R. kaempferi to their pedigree. Gable Hybrids are also tolerant of heat and drought. They have an extended flowering period and are reliably evergreen in the winter.

The compact, rounded to upright plants have small, shiny, elliptic to oval leaves....

(Girard Hybrid Azalea)

Renowned for their cold hardiness, these compact evergreen azaleas were bred at the Ohio-based Girard Nursery. They are also noted for large blooms on compact disease-resistant plants.

In spring, they put forth large, often ruffled flowers that can be red, pink, fuchsia, salmon, white or yellow. The abundant, usually funnel-shaped flowers cluster near the ends of the branches. The flowers are single, double, semi-double or hose-in-hose (two "stacked" sets of petals). Their small oval glossy...

(Glenn Dale Hybrid Azalea)

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...

(Greenwood Hybrid Rhododendron)

Bred to thrive in the mild climate of the coastal Pacific Northwest United States, these evergreen azaleas were developed after 1960 by Bill Guttormsen of Canby, Oregon, They are the result of crosses between Gable, Glenn Dale, Kurume, and other hybrids. Greenwood Hybrids bear clusters of funnel-shaped flowers on dense compact plants in spring. The funnel-shaped, often ruffled flowers come in a wide range of colors and may be single, semi-double, double, or hose-in-hose (with two superimposed sets...
