Botanical Name

RIBES rubrum 'Raby Castle'

Plant Common Name

Red Currant

General Description

Grown for its flavorful berries, red currant is a small to medium-sized deciduous shrub from Eurasia. Introduced in England about 1820, 'Raby Castle' produces medium-long bunches of currants that ripen to bright red in early to midsummer, rather late in the red currant season. They are preceded by drooping clusters of inconspicuous green flowers in early spring. The tart, juicy, translucent fruits are excellent for jellies, sauces, and cooked desserts, and are also eaten 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. 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). This cultivar is susceptible to rust.
