Family

Grossulariaceae

Botanical Name

RIBES sanguineum 'Ubric'(WHITE ICICLE™)

Plant Common Name

Red-flowered Currant

General Description

A vigorous deciduous shrub from far western North America, Ribes sanguineum has given risen to several showy cultivars. White Icicle™ covers itself with dangling conical clusters of flower buds that open to small starry white flowers in late winter and early spring as the leaves emerge. They attract hummingbirds, butterflies, and bees. Plants make a fountain-like mass of branching upright stems clothed in pungently scented, bright green, lobed and textured leaves. The foliage turns reddish hues in fall. Blue-black berries ripen in summer, attracting wildlife.

For best growth and fruiting, plant White Icicle™ in full sun to partial shade and well-drained soil. In climates with hot summers, choose a site that has little or no afternoon sun. Mulch the plant to help conserve moisture and cool the soil. To encourage more bloom, remove old stems and prune remaining stems to two strong buds after flowering.
