The large double white flowers of this Beltsville evergreen azalea are borne in clusters in early to mid-spring. The wavy-edged, yellowish-throated blooms are hose-in-hose (with two "stacked" whorls of petals). This chest-high shrub has elliptic olive-green leaves.
The Beltsville Hybrid azaleas were developed in the late 1950s by Guy E. Yerkes and Robert L. Pryor of the United States Department of Agriculture’s Beltsville, Maryland, Station. They are complex Rhododendron hybrids involving...
One of the so-called Indian hybrid azaleas, this evergreen shrub bears showy clusters of large double pink flowers with deep pink veins and pinkinsh-white margins. The unscented, broadly funnel-shaped blooms appear from late winter into spring, but may also bloom from late fall through winter in frost-free districts. The compact mounded plants have elliptic dark green leaves. This cultivar is usually offered under the name 'California Sunset.'

Glowing rose-red flowers cover this compact upright evergreen azalea in mid-spring. The broadly funnel-shaped blooms of 'Hahn's Red' are unscented. The hairy oval leaves are glossy dark green. This cultivar slowly forms a rounded waist-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, Hampton Beauty Azalea, Pericat Hybrid Azalea)
Gorgeous large rich pink flowers with red-flecked upper lobes adorn this Pericat azalea from mid- to late spring. The clustered blooms have partially petal-like sepals, giving them the appearance of semi-double flowers. This broad rounded chest-high shrub has small elliptic medium-green leaves.
Comprising more than 40 named cultivars, the Pericat hybrid azaleas likely have Kurume and Belgian Indica hybrids in their lineage. They prefer partial shade and highly organic acid soil that is evenly...

This Brooks Hybrid azalea bears large rose-red flowers with a flaming red throat. The late spring blooms are hose-in-hose (with "stacked" whorls of petals). This compact rounded cultivar has elliptical leaves that hold their glossy-green color year-round.
The product of crosses between Belgian Indica, Southern Indica, Kurume, and other hybrid azaleas, Brooks Hybrids are heat- and drought-tolerant evergreen azaleas bred in Modesto, California.
Brooks Hybrid azaleas prefer partial shade...
Introduced by Hines Nursery of Irvine, California, these tender evergreen azaleas result from crosses among Belgian Indica Hybrids and other hybrid azaleas. They were selected for their compact rounded habit and their profusion of large funnel-shaped flowers from later winter into early spring. The clustered single, semi-double, or double flowers are sometimes fragrant. Flower colors include pink, purple, and rose. The small hairy lance-shaped leaves are glossy-green. Although developed partly for...

Bearing showy clusters of large single white flowers in early to mid-spring, 'Helen Close' is one of the more than 400 named 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 have a greenish-yellow blotch that fades to white. The spent flowers drop rather than persisting on the plant. This dense, rounded, chest-high shrub has elliptic medium-green...
