      Since Cascara (also known as Chitum) prefers a shady, moist condition, it is often found growing as an understory tree with Vine Maple and Red Alder. The 1/4” black berries, while not especially tasty for humans, are attractive to raccoons and a variety of birds. The bark was used medicinally by Northwest natives and continues to be harvested for its laxative properties. (Portland Plant List, 2016)
