RHODODENDRON 'Phyllis Korn'

David C. Royster

Family

Ericaceae

Botanical Name

RHODODENDRON 'Phyllis Korn'

Plant Common Name

Phyllis Korn Rhododendron, Rhododendron

General Description

A hardy, handsome, and showy-flowered hybrid, this 1981 introduction bears large spherical clusters of white blooms in mid-spring. The wide-flaring funnel-shaped flowers have a red blotch on their upper lobe which fades to pale greenish yellow. This strong upright head-high shrub has large, elliptic, glossy dark green leaves.

Like most rhododendrons, 'Phyllis Korn' favors chilly winters, moderate summers, partial shade, and highly organic, well-drained, acid soil. Plant it shallowly and mulch well to conserve moisture and suppress weeds. Do any necessary pruning directly after the flowers fade, before new flower buds form. Try to site it where it has room to grow to full size.

This handsome evergreen works well in shrub plantings, mixed borders, and naturalistic shade gardens.
