About

Crataegus douglasii is a North American species of hawthorn known by the common names black hawthorn and Douglas' thornapple. It is most abundant in the Pacific Northwest.

Where it grows

The thorny shrub is native to northern and western North America, most abundantly in the Pacific Northwest. It grows in varied habitats from forest to scrubland, including moist open places, forest edges, thickets, shorelines, streamside areas, roadsides and coastal bluffs at low to middle elevations.

Uses

The edible fruits were a good food source for Native American peoples such as the Cheyenne and Nlaka'pamux. The Syilx/Okanagan use the ripening of the black hawthorn as an indicator that, in the highlands, black mountain huckleberries are ripening, too.
