Crataegus phaenopyrum (Washington Hawthorn) is a small, low-branching, deciduous tree of graceful habit with a dense, broadly oval to rounded crown. In late spring to early summer, it is generously covered in dense clusters of creamy-white flowers and provides a spectacular floral display. In summer, its strongly horizontal branches are clothed with glossy leaves adorned with 3-5 pointed lobes. Like most hawthorns, they are well armed with slender thorns, about 1-3 in. long (2-7 cm). In the fall, the foliage turns glorious shades of scarlet, orange and purple. Adding their charm to the show are shiny red round fruits clustered among the glowing leaves. Attractive to wild birds, they adorn the branches well into winter. It is the last hawthorn to flower and is also the most heat tolerant hawthorn. More elegant and delicate than others, it is also one of the least prone to fireblight. The flamboyant flowers and blazing fall color make it one of the showiest and most desirable hawthorns for planting.
