Mahonia nervosa, commonly known as dwarf Oregon-grape, Cascade barberry, Cascade Oregon-grape, or dull Oregon-grape, is a flowering plant native to the northwest coast of North America from southern British Columbia south to central California, with an isolated population inland in northern Idaho.[4][5][6] It is especially common in second growth, Douglas-fir[7] or western redcedar forests, making use of those pools of sunlight that intermittently reach the ground.
Some authors place the entire genus Mahonia within the genus Berberis.[8][9][10]
The plant was collected by Lewis and Clark during their famous expedition to the West before being described for science in 1813.[11][12]
Description
)
It is an evergreen shrub with short vertical stems, mostly under 30 cm (12 in), while the leaves reach higher, rarely up to 2 m (6 ft 7 in) tall. The leaves are compound, with 9–19 leaflets; each leaflet is strongly toothed, reminiscent of holly, 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. The flowers and fruit are like those of other Oregon-grapes, and are equally sour-tasting.
Uses
Some Plateau Indian tribes drank an infusion of the root to treat rheumatism.[13] The Yana people dried and ground the fruits to make a mush. They can also be dried and eaten like raisins.[14]
