Comment: Green hawthorn is a small tree, 20-35’ tall, with a dense, rounded crown, often forming thickets. A facultative wetland species, it can be found growing in bottomland forests, near swamp margins, or other hydric communities. Bark of trunks pale brown to silvery gray, breaking into narrow scales with age, eventually exfoliating to reveal orange inner bark. Twigs brown, glabrous, often completely spineless, but when present spines are 1-1.5 inches long. Leaves ovate-oblong, 1-2.5” long and 0.5-1.5” wide, simple, alternate, base cuneate or rounded, apex, acute to acuminate, margins serrate, sometimes with shallow lobes toward the base, glabrous above, tufts of hairs present where leaf veins join. Flowers showy, in small white corymbs in spring. Fruits are small pomes, 0.25”, globose to sub-globose, red-orange, fall, persisting through winter. Seed collected from 3 plants.
