About

Berberis nervosa, commonly known as dwarf Oregon-grape, Cascade barberry, Cascade Oregon-grape, or dull Oregon-grape, is a North American flowering plant.

Where it grows

It is native to the northwest coast of North America from southern British Columbia south to central California, with an isolated population inland in northern Idaho. It is especially common in second growth, Douglas-fir or western redcedar forests, making use of those pools of sunlight that intermittently reach the ground.

Uses

The Yana people dried and ground the fruits to make a mush. The fruits may also be dried and eaten similarly to raisins or used in preserves such as jelly.
