Mountain Grape is a native plant on the North American west coast from British Columbia to northern California, occurring in the understory of Douglas-fir forests & in brushlands. It is the state flower of Oregon. Some regard it as more truly belonging to the Mahonia species (to which Barberry or Berberis is related) but should easily be distinguished when purchasing as it is seldom sold under any other name than Mountain Grape Root or Oregon Grape Root. It is commonly used traditionally as an effective alternative to the threatened goldenseal. Both plants similarly contain the alkaloid berberine.
