Family

Rosaceae

Botanical Name

RUBUS canadensis

Plant Common Name

Smooth Blackberry

General Description

An ancestor of many blackberry cultivars, this native of eastern and central North America is a medium-sized to large deciduous shrub with arching nearly thornless stems. Inconspicuous five-petaled white flowers appear in spring, followed in summer by shiny cylindrical black berries. Although edible, they are rather sour. The compound leaves usually have five leaflets.

This tough cold-hardy shrub prefers well-drained acidic or neutral soil and full to partial sun. It is useful for the wild garden and for hybridizing.
