Plant Common Name

American Raspberry

General Description

The American red raspberry is an upright, deciduous, prickly shrub native to North America and Eurasia. It has been long cultivated for its juicy tasty red or yellow berries. Its many cultivars vary by fruit color, flavor, and harvest time. Plants produce canes that bear in their second year but also yield a first-year fall crop in the case of everbearing cultivars.

The pinnately compound leaves of this deciduous shrub are composed of five to seven leaflets, on average. Each leaflet is rich green, has prominent leaf veins and toothed edges. The upright canes are lined with thorns. New canes are produced via suckers that spread from the base of the plants. New canes typically do not produce flowers in the first year but fruit and flower in the second. The white, five-petaled flowers are produced in spring and fruits appear in summer or fall. Bees and other insects are the chief pollinators. The red, thimble-like, aggregate fruits are juicy, sweet and much loved be people and wildlife alike.

Red raspberries grow best in full sun and well-drained, moderately fertile soil. They cold winters and gradual springs to flower and fruit well. Partial shade and cool mulch may be required for plants grown where summers are hot. Prune second-year canes to the ground in fall and pull and cut back any suckers that have outgrown their designated growing space.

No culinary garden is complete without a well-maintained row of sweet, red raspberry bushes. The shrubs can be trellised to keep them more manageable and easier to maintain.
