Wikipedia Abstract

Crataegus phaenopyrum is a species of hawthorn commonly known as Washington hawthorn or Washington thorn. It is widely grown as an ornamental plant, and can reach 10 m in height. The small red berry-like fruit grow closely together in large clusters and are food for squirrels and birds. They have a mild flavor and can be eaten raw or cooked. As with other species of hawthorn, the wood is hard and can be used to make tools.
