Black Hawthorn (Crataegus douglasii) is a large shrub or small deciduous tree with a long trunk and round-topped crown of spreading branches. Like other Hawthorns, white blossoms will appear on the tree in May and June that are beautiful, but unpleasantly fragrant. Although unpleasant to us, the blooms attract a host of insects and pollinators before giving way to deep red fruits that turn black by the end of summer. These fruits are edible and have been shown to improve cardiovascular health and lower blood pressure. The foliage turns attractive shades of red, yellow, or orange in the fall and the berries persist on the shrub for a long time, making this a handsome oranamental in the landscape throughout the year. Grow as a speciman plant in ornamental beds or edible plantings, or use as a hedge or privacy screen. This plant does have thorns and will sucker to form thickets. Plant in an area where spread is desired, or prune suckers at the base regularly to control this growth.
