RHODODENDRON 'Edith Bosley'

James Burghardt

Family

Ericaceae

Botanical Name

RHODODENDRON 'Edith Bosley'

Plant Common Name

Edith Bosely Rhododendron, Rhododendron

General Description

One of the few rhododendrons to offer deep purple flowers and exceptional cold hardiness, this hybrid cultivar bears its large domed clusters of funnel-shaped blooms in mid-spring. The flowers have a reddish purple rim and throat and a maroon-spotted upper lobe. This upright, rounded, head-high shrub is furnished with elliptic glossy evergreen leaves.

Like most rhododendrons, 'Edith Bosley' prefers some shade and a highly organic acid soil that is evenly moist but well-drained. Plant it shallowly and mulch well to conserve moisture and suppress weeds. Do any necessary pruning directly after the flowers fade, before next year's buds form. Try to site it where it will not need to be pruned back.

This handsome and hardy rhododendron is ideal for mixed borders and shrub plantings.
