flowering plant native to the northwest coast ofNorth America from southernBritish Columbia south to centralCalifornia , with an isolated population inland in northernIdaho .It is an
evergreen shrub with short vertical stems, mostly under 30 cm, while the leaves reach higher, rarely up to 2 m tall. The leaves are compound, with 9-19 leaflets; each leaflet is strongly toothed, reminiscent ofholly , and somewhat shiny, but less so than Tall Oregon-grape. The leaflets do not have a single central vein as in that species, but several veins arranged fan-like, branched from the leaflet base, hence the epithet "nervosa". Theflower s andfruit are like those of other Oregon-grapes; like them they are edible but just as sour.It is able to grow under mature stands of
Douglas-fir or Western Redcedar making use of intermittent pools of sunlight that reach the ground.External links
