Rubus canadensis

Common Name(s):

Phonetic Spelling

Description

The Genus Rubus includes blackberry, dewberry, and raspberry and most members of the Genus share the traits of thorny or bristly stems and compound leaves. Also, flowers and fruit appear on last seasons canes (branches), seldom on new shoots, which means one must be cautious when pruning and not remove the canes that will yield next year's berries. There are differences, however, among species; for example, some are erect or arching shrubs up to 8 feet high and others trail on the ground like vines. Some, such as dewberries, produce fruits in the spring while blackberries and raspberries fruit during the summer. In general, Genus Rubus contains some of the most important plants for wildlife in the southeast.

Rubus canadensis, or Smooth blackberry, has almost completely smooth stems that are free of prickles and spines. Leaves are smooth with few hairs on the underside. The fruit is edible raw or cooked in pies or jams and is sweet, juicy and richly flavored compared to other species of blackberries.The plant spreads by rhizomes, which are typically found about 3 to 4 inches below the surface. Because it grows well in relatively barren conditions and sprouts after fire, smooth blackberry is used for reclaiming disturbed areas. It is an understory plant commonly found on forest edges, in meadows and fields, ridges or ledges, shores of rivers or lakes, shrublands thickets, and wetland margins. Its range extends from Newfoundland to Ontario and along the Atlantic Coast south to Georgia and inland to Kentucky and Tennessee. It is present in mature spruce-fir forests in North Carolina.

Dense colonies of these shrubs provide excellent cover for nesting birds. The canes create nearly impenetrable thickets where birds, rabbits, and other animals hide. Game birds, songbirds, raccoons, chipmunks, and squirrels eat the fruits. The nectar and pollen of the flowers attract many kinds of insects, especially long-tongued and short-tongued bees. This plant is moderately resistant to damage from deer. It provides excellent cover year round. Butterflies and other insects are attracted to the blooms. The fruits are relished by songbirds, small mammals, foxes, racoons and black bears. During the winter, birds and small mammals eat the seeds left from rotten fruit. White-tailed deer and rabbits browse the leaves.

The plant has no known insect or disease problems, but it can become aggressive and difficult to eliminate. Because it is so successful and can spread easily, use caution when selecting a planting site. Herbicides may be required to completely eliminate the plant.
