Crataegus viridis Linnaeus var. viridis . Green Hawthorn, Greenhaw. Phen: Late Mar-late Apr; Sep-Nov. Hab: Swamps, bottomland forests, alluvial woodlands, streamsides, wet flatwoods, and uplands where soils are often basic to calcareous. Dist: MD to n. FL, w. MO, c. TX; absent or rare on Appalachian Plateau.

ID notes: One of our largest hawthorn species, frequently reaching treelike proportions (5-10 m tall, trunk 10-40 cm diameter). The orange-red fruits often persist on the bare branches into winter, sometimes until the following spring. Bark of the trunk is usually mottled with patterns of gray, reddish-brown, and greenish-gray coloration, due to the dehiscing layers of scales and plates.
