Cascade Oregon Grape is an excellent understory plant in partially shaded areas.

This species has the same beautiful flowers and fruit as does Tall Oregon Grape but has longer leaves and reaches heights of only 2.'

The flowers are highly aromatic, and, like all Mahonias, the autumn display is spectacular, with burgundy, red, gold and bronze.

This plant is widespread in open forest areas or in the understory from BC to California and in Idaho as well.
