Rubus leucodermis (Blackcap Raspberry, Black Raspberry, Whitebark Raspberry, or Blue Raspberry) is a species of Rubus in the Rosaceae family. It is found in California, Alaska, and New Mexico of the United States, British Colombia of Canada, and Mexico. It is closely related to Rubus occidentalis.
It is a deciduous shrub that grows from .5-2 meters tall, with thorny shoots. The tips of the 1st year canes (primocanes) often grow downward in the fall, and form tip layers which become new plants. The leaves are pinnate with five leaflets on stems in their first year, or 3 leaflets with branches with the rare purple to white flowers. The fruit, a raspberry, is 1-1.2 cm in diameter, red to purple at first, but nearly black when ripe.
This raspberry forms natural hybrids like several in the Idaeobatus subgenus.
