Washington Hawthorn
Crataegus phaenopyrum
Rosaceae · broadleaf · introduced
Washington hawthorn is the hawthorn with the best fall color, orange and scarlet, and the most persistent fruit display: small, glossy red berries in dense clusters that hold through winter and into early spring, providing food for cedar waxwings, robins, and other fruit-eating birds well into the lean months. Native to the middle latitudes of the eastern United States, it grows as an upright small tree with a thorny, twiggy crown and white flowers in late spring. The thorns are long and sharp, which makes it an effective barrier planting but a poor choice near walkways.
In Western Washington, Washington hawthorn tolerates a wide range of soils and light conditions, from full sun to partial shade, and handles urban stress well. The fall color alone sets it apart from other hawthorn species available in the regional trade, and the winter fruit display is genuinely spectacular, sometimes lasting until the following spring's bloom. No significant disease or pest concerns are flagged in the regional knowledge base. The thorns are a management consideration, not a fault, they make pruning unpleasant but also make the tree effective as a boundary or deterrent planting. If you want a small tree that feeds birds through winter and provides fall color that hawthorns are not supposed to have, Washington hawthorn is the one.
