Rubus idaeus subsp. idaeus
Common Name(s):
- Phonetic Spelling
- ROO-bus eye-DAY-ee-us
- Description
-
Red raspberry is an erect to spreading perennial shrub in the rose (Rosaceae) family primarily grown for its very tasty fruits. This variety is native to temperate Europe and has naturalized in parts of the northern USA and Canada.
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. Because it is a low-lying thorny shrub, wild raspberries may not do well in a garden setting and, if not properly cared for, can easily spread to form a thorny thicket.
Red raspberry prefers organically rich, slightly acidic, moist but well-drained soils in full sun to part shade. It is intolerant of wet soils which can cause root rot.
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.
Information on blackberry cultivation for home gardeners is available in the NC State Extension publication Raspberries in the Home Gaden
Insects, Diseases, and Other Plant Problems: Spotted wing drosophilla 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.
