Black Haw Bark | Cut
This native plant is a branched woody shrub or small tree up to 15’ tall. The young bark of small branches is gray and slightly rough, while the old bark of the trunk or larger branches is grey and rough with flat-topped plates. The opposite leaves are up to 3” long and 1” across; they are ovate or ovate-obovate, and glabrous on both their lower and upper sides, and finely serrated along their margins. The
Slender petioles are up to 1” long and reddish. The buds of these leaves are short. Cymes of flowers of about 3-5” across develop from the axils of the leaves; each cyme is very branched, but sessile at the base. Each flower is about ¼” across, it has white petals that are well-rounded and longer than the sepals. There are 5 long stamens with slender white filaments and yellow anthers, and a small pistil at the center of the flower that is cream-colored at the base. The blooming period occurs from mid-to late spring. The flower is replaced by a fleshy ovoid drupe, about 1/3” long, this drupe becomes blue-black at maturity, sometimes with a whitish bloom. Inside each drupe, there is a single stone ( a seed with a hard coat) that is flat on one side and convex on the other. The drupes are sweet and edible, although somewhat thin-fleshed because of their stones. The root system consists of a branching woody taproot.
It prefers light shade to partial sun, mesic to dry conditions, and soil that is loamy, clayish-loamy, sandy-loamy or somewhat rocky.
