This is a dense, round-headed tree, to 30 ft., with slender thorns up to 3 in. long. Broadly triangular, deciduous leaves turn yellow to orange or scarlet in fall. Short trunk and regular, rounded crown of upright branches, abundant small flowers in spring, many small, round, red fruits, and brilliant autumn foliage; hairless throughout. Clusters of white, apple-like blossoms precede bright-red berries which persist into winter. Trunk bark is silvery-gray and scaly; twigs are a flaky, red-brown. There is a strong horizontal branching habit.
One of the showiest and most desirable hawthorns for planting. In the early 19th century, it was introduced into Pennsylvania from Washington, D.C., as a hedge plant and is thus called Washington-thorn. The Latin species name refers to the pearlike foliage.
