- Description
-
This genus, the brambles, has two main varieties, Rubus idaeus var. idaeus (European raspberry) which is native to Eurasia and Rubus idaeus var. strigosus (American red raspberry) which is native to a large part of North America. These two cultivars, or a cross of both, are typical of commercially grown raspberries.
Rubus idaeus var. idaeus, or Red raspberry, is an erect to spreading perennial shrub in the Roseaceae family primarily grown for its very tasty fruits. First-year canes (stems) bear only leaves while lateral second-year canes produce flowers and fruits. Prune to keep plants well-maintained, but care must be used to avoid pruning the second-year growth that will bear fruit. It is generally best to prune out old, summer-bearing canes as soon as fruiting is over to encourage new canes. Each cane lives only two growing seasons before dying.
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. When grown for harvest of its raspberry fruits, raised beds should be considered in areas with heavy clay soils.
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.
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.
