From Native Plants PNW:
Tall Oregon Grape is native along the Pacific Coast from southern British Columbia to Northern California. Its range stretches across eastern Washington to the Idaho panhandle and Western Montana. Tall Oregon Grape grows to about 6-8 feet (2-2.5m) tall and spreads by underground stems to about 5 feet (1.5m) wide. It may grow slowly at first as it becomes established, then will quickly grow to its mature size. Tall Oregon Grape is usually found on somewhat dry, rocky, open sites.
Tall Oregon Grape has long been recognized as an outstanding landscaping choice. It can be used as an accent plant or as a screen. Its bronzy foliage, bright yellow, lightly scented flowers and bold texture can make an attractive addition to any landscape, but because of its prickly nature it should not be planted along walkways, where people may inadvertently brush up against it.
Bloom Period: April-May. Fruits ripen September-October.
Birds eat the berries of Oregon Grape. The foliage provides cover for many species and browse for deer. The flowers are very attractive to insect pollinators and hummingbirds.
