A hardy hybrid that bears large domed clusters of fiery red flowers in mid- to late spring, this evergreen rhododendron is actually a group of several clones that resulted from the same cross. The wide-flaring, wavy-edged, funnel-shaped flowers are unscented. This rounded head-high cultivar has large elliptic dark green leaves with pointed tips.
Like most rhododendrons, 'Vulcan' prefers some shade and a highly organic acid soil that is evenly moist but well-drained. Plant it shallowly and...

Sumptuous deep red flowers cover the dense upright evergreen azalea 'Ward's Ruby' in mid-spring. The unscented, broadly funnel-shaped flowers have a darker zone at the base of their upper lobes. The oval glossy dark green leaves take on burgundy and bronze tints in winter. 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,...

(Briggs Hybrid Azalea, Deciduous Azalea, Western Lights Azalea)
A polyploid mutation of the Northern Lights Series cultivar 'Orchid Lights,' this extremely hardy deciduous azalea improves on its parent it its larger flowers and thicker, lusher, more colorful leaves. A Briggs Nursery introduction, it bears dense spherical trusses of purplish-pink flowers in late spring. The wavy-edged, broadly trumpet-shaped flowers have red-speckled upper lobes. This prolifically blooming cultivar gradually forms a dense compact upright shrub with bluish-green leaves that turn...

(Weston Hybrid Azalea, Weston's Aglo Azalea)
Characterized by showy fragrant flowers, late spring or early summer bloom, and superior cold-hardiness, these deciduous azaleas were developed and introduced by Weston Nurseries of Hopkinton, Massachusetts. Hybrids of eastern North American native azaleas including Rhododendron viscosum, R. prinophyllum, and R. arborescens, they bear showy heads of single pink, orange, yellow, red, or white blooms. The wide-flaring funnel-shaped flowers often have contrasting...
