Crataegus phaenopyrum
Washington hawthorn

Culture: Well-drained, slightly acidic to alkaline soils in full sun are best for this species. Although this species prefers moist soils it will tolerate dry sites. It is resistant to sulfur dioxide pollution but is intolerant of road salt. As with other hawthorns, this species is moderate to slightly difficult to transplant, and is best pruned in early spring or winter.

This species is generally less troubled by the various hawthorn disease and insect problems. It is often listed as resistant to cedar hawthorn rust, but I have observed specimens with considerable distortion of stem growth in severe years.

Usage: This tree is an excellent choice for specimen use, where its showy flowers, fruits and fall color can be enjoyed. Consider an appropriate background to show off the orange-red fruits.
