- Description
-
Red raspberry is an erect to spreading, perennial shrub in the rose family (Rosaceae), primarily grown for its tasty, edible fruits. This subspecies is native to temperate Europe and northern Asia. The species and subspecies epithet were unexplained by the author but likely refer to the nymph Idaea of Greek mythology.
Red raspberry grows 3 to 9 feet tall and wide. It prefers organically rich, slightly acidic, moist but well-drained soils in full sun to partial shade. It is intolerant of wet soils, which can cause root rot. Propagate by division or stem cutting. Information on raspberry cultivation for home gardeners is available in the NC State Extension publication Raspberries in the Home Garden.
First-year canes (stems) bear only leaves, while lateral second-year canes produce flowers and fruits. Flowers bloom in clusters in spring but are occasionally solitary, and are generally white but sometimes pink to rosy-purple. Fruits ripen in summer. There are many cultivars available with improved fruit and taste that are appropriate for the home garden. Be sure to check the chill hour requirements before planting. Most raspberries do best in the north or in the mountains.
Because it is a low-lying, thorny shrub and can easily spread to form a thorny thicket, red raspberry requires some care and maintenance in a home garden setting. If properly cared for, it can be used as a barrier or screen for privacy. It also works well in a recreational play area or children’s garden. Because its flowers and fruit attract pollinators and wildlife, it is perfect for a butterfly or pollinator garden.
Insects, Diseases and Other Plant Problems: Spotted wing drosophila can be a problem. Cane borers and crown borers are potentially serious insect pests. Anthracnose, botrytis, root rot and other fungal diseases can cause serious problems and may require treatment. It is also weedy.
