Plant Common Name

White Currant

General Description

Grown for its flavorful berries, red currant is a small to medium-sized deciduous shrub from Eurasia. The albino-fruited cultivar 'White Grape' originated in England about 1849. Largest fruited of the white currants, it produces long bunches of berries that ripen to translucent pearl-white in early summer. They are preceded by drooping clusters of inconspicuous green flowers in early spring. The mildly tart, juicy, translucent, tender-skinned fruits are excellent for jellies, sauces, and cooked desserts, and are among the best currants for eating fresh. They are high in vitamin C and other antioxidants. Plants are self-fruitful. The toothed, three-lobed, maple-like leaves are medium-green and hairless. This cultivar forms an upright, slightly spreading shrub. Red currant plants may escape gardens via self-sowing.

For best growth and fruiting, plant this shrub in full to partial sun and moist well-drained soil. Extremely cold-hardy, it requires 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 red currant in mixed edible plantings and hedges. As a possible 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).
