Creeping Oregon Grape, also known as Low Oregon Grape, is evergreen, hardy, and drought-tolerant with drooping sprays of fragrant yellow blooms that support an array of bees, hummingbirds and other pollinators, then mature into berries for backyard birds and wildlife. Its leaves are softer and rounder than its relative the Tall Oregon Grape, and provide seasonal color to the garden with a dull bluish green hue in summer, that turn to shades of bronze, maroon and red in winter.

Gardening with Creeping Oregon Grape: Many native plant purists pass over this plant, since it is native east of the Cascades, and historically not present in the Portland Metro area. However, this species is significantly more versatile and able to tolerate increasingly hot and dry summers than its locally native cousins. In part sun, it will flourish, but it can also tolerate full sun, especially if provided a little supplemental moisture, as well as full shade - even dry shade. It spreads slowly, but once established, is exceptionally hardy and makes a perfect addition to your pollinator garden, as a groundcover under tall trees or in other dry corners of the garden.
