Source: Magness et al. 1971

Several species of Rubus have contributed to the cultivated blackberry. Canes are erect or semi-erect, and in cultivation are supported on a trellis. Canes grow from the crown one year, fruit the following season, then die. They may grow to 15 or more feet in length. Most varieties are heavily thorned, but thornless sports and varieties are now available. Fruits are borne in loose clusters on laterals that grow from the canes. They consist of numerous small seeds, each imbedded in a juicy pulp, and all adhering to a fleshy base. The base separates from the plant when the fruit is harvested, in contrast to raspberries, in which the base or receptacle is retained on the plant. Fruits are near globose to cylindrical in shape, 0.5 to 0.75 inch in diameter and 0.75 to 1.5 inches long. Leading varieties are Oregon Evergreen, Himalaya and Marion.
