Cascade barberry

Scientific name
Berberis nervosa
Also Known As
Mahonia nervosa, Cascade Oregon grape, dwarf Oregon-grape, dull Oregon grape
Plant Family
Cascade barberry is a flowering evergreen shrub, native to the Northwest coast of North America, and grows up to 6.5 feet tall.
Identification Hints

Cascade barberry is often found in second growth below Douglas-fir or western redcedars.  Leaf veins are fan-like hence the name nervosa.   Leaflets on the plant are sharply toothed like holly, but not as shiny as for Berberis aquifolium (Tall Oregon grape).  Both flowers and fruit are similar to the other Oregon grapes (sometimes spelled using a hyphen: Oregon-grapes).
