Iranian blackberry is an aggregate fruit that is composed of many smaller fruits called drupes.

Blackberries are red and hard when they are immature and turn black and shiny when they ripen.

The canes are a dull green color and often have thorns; however, there are thornless varieties.

The compound leaves are heavily toothed on the edges, somewhat prickly, and bright green in color.

Blackberry and raspberry plants may be difficult to tell apart; however, blackberry leaves are light green in color on the underside, while raspberries have silvery undersides.
