Botanical Name

RIBES nigrum 'Boskoop Giant'

Plant Common Name

Black Currant

General Description

Grown for its flavorful berries, black currant is a small to medium-sized deciduous shrub from Eurasia. An heirloom variety introduced before 1885, 'Boskoop Giant' produces clusters of plump, juicy, exceptionally flavorful, few-seeded fruits. The round, tart, long-lasting berries ripen purple-black in early to midsummer, becoming sweeter as they mature. They are preceded by drooping clusters of inconspicuous greenish and purple flowers in spring. The fruits are excellent for preserves, pies, and sauces. The toothed, three-lobed, maple-like leaves emit a pungent odor when bruised. This shrub has a relatively rangy, upright, spreading habit.

For best growth and fruiting, plant this shrub in full to partial sun and well-drained soil. It needs some winter chill to perform well. In climates with hot summers, choose a site that has little or no afternoon sun. Mulch the plant to help provide even moisture and cool the soil. Remove two-year old stems to make room for new stems that are more productive and to allow sun to reach all the stems.

Use black currant in mixed edible plantings and hedges. As an alternate host for white pine blister rust, it may be banned in areas where that disease is extant (http://plantclinic.cornell.edu/FactSheets/wpineblister/wpineblister.htm). Although some black currant cultivars are rust-resistant, 'Boskoop Giant' is susceptible.
