Black Hawthorn (Crataegus douglasii) is a deciduous, thicket-forming shrub or small tree that grows anywhere from 20-40 feet tall. It is a common plant in Oregon and Washington on both sides of the Cascades, growing in moist, well-drained soils. The black hawthorn is an important species for wildlife, attracting pollinators and providing protected nesting and edible fruits for birds and other small wildlife.
Leaves are 1.5-3 inches long and up to 1.5 inches wide, doubly serrate, ovate, and sometimes lobed. Small white flowers bloom in clusters from late spring to early summer. The small, oval fruits are purple-black when ripe, one quarter to a half inch in size. This attractive tree turns yellow, orange, and red in fall.
