Rubus hispidus, with the common names swamp dewberry, bristly dewberry, bristly groundberry, groundberry, hispid swamp blackberry or running swamp blackberry, is a dewberry species of Rubus.

The plant grows in moist or sometimes dry soils, ditches, swales or open woods in central and eastern North America, from Ontario and the Maritime Provinces to South Carolina and Texas.[1]


Rubus hispidus reaches a height of from 0.2 m to 1 m tall, and is in leaf all year. The twigs are red and bristled.

It has small flowers with five white rounded petals. The fruit is a raspberry (an aggregate of drupelets), red or dark purple when ripe.

Unripe berries.


A dull blue dye can be created from its berries. It also can be used as an astringent.

The berries are rather bitter for culinary use, and so this plant is generally not cultivated.
