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.
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.
