Occasionally, blackberries (Rubus
spp.) are found along the edges of prairies. It can be difficult to tell the different species apart. This is one of the more common blackberries in Illinois. The fruits of Common Blackberry tend to be a bit larger and more elongated than those of other blackberries, and they usually have an excellent flavor. This blackberry is distinguished from other blackberries by the numerous glandular hairs on the peduncles and pedicels of its elongated racemes of flowers. Furthermore, its mature leaflets are usually no more than twice as long as they are wide. These two characteristics distinguish the Common Blackberry from other Rubus spp.
in Illinois. Return
