utility friendly tree icon WASHINGTON HAWTHORN
Crataegus phaenopyrum


General Notes


     Utility friendly tree. A small flowering accent tree with a more graceful branching habit than other hawthorns. The flowers often attract bees, but the berries in fall provide a showy accent. It is dependable in ordinary soils, with moderate moisture, in full sun. It may suffer from occasional aphids, but is the least susceptible to fireblight of the hawthorns. It is quite hardy. It may require regularly scheduled light top-trimming (but not necessarily shearing) of vigorous top shoots to maintain its height below 25'. Has thorns. Native to Southeastern United States.
