Creeping Oregon-grape or creeping barberry is a stoloniferous, sprawling evergreen of stiff habit with small, fragrant, yellow flowers in drooping racemes, followed by showy, purple fruit. The leathery, holly-like, compound leaves are a muted green, some turning mauve, rose, and rust-colored in winter. The plant grows 1-3 ft. in height.

A beautiful foliage groundcover for shade in the western mountains of the continent, Creeping Barberry has muted green leaves that are occasionally shades of pastel pinks, purples, and oranges. It thrives in good garden soil, but does not tolerate high heat or drying wind. Its yellow spring blooms attract pollinators and its berries attract birds.
