Cascara (Frangula purshiana) is found along the Pacific coast from British Columbia to northern California along forested riverbanks and in other moist locations. 

A hardy, compact, attractive tree, it is often planted in Portland’s parking strips.  In the spring it produces clusters of small, green-white flowers.  In late autumn, the leaves turn a delicate yellow and persist through many a winter storm.  While it can tolerate dry conditions, it does better with some summer water.

The flowers attract many pollinators in early summer such as Lorquin's admiral butterflies.  Pale swallowtail butterflies lay their eggs on the leaves.  Birds enjoy the fruit, but they are toxic to humans and should be avoided.
