Comments
"Creeping Mahonia is a typical mahonia with conspicuous matt blue berries and shiny leaves. It grows as a subshrub. The yellow flowers appear in the middle of spring, and the blue berries in early summer. It is a hardy plant, tolerant of drought, frost, and heat, so it is popular with gardeners. Berries and foliage are resistant to attack by deer, and although it is evergreen, in fall the leaves turn an attracting bronze."

Uses
The berries are edible but are considered bitter, and used to make jellies.

The Tolowa and Karok Indians of Northwest California used the roots for a blood and cough tonic. The Hopi, Paiute, Navajo, Shoshoni, Blackfoot, Cheyenne, Mendocino, and other tribes also used the plant for medicinal, food, and ceremonial needs. Native Americans also used the wood of the stem to produce yellow dyes to stain woven baskets.
