Description of Plant(s) and Culture

Crampbark is a large, handsome, upright shrub or tree; to 12 feet high; leaves maple-like, with 3-5 lobes, hairy beneath. The leaf stalks have a narrow groove, and a disk-shaped gland. Leaves have three lobes and are broadly wedge-shaped. White flowers in a rounded head, to 4 inches across; April to June. Flowers are showy and are succeeded by red, very acid berries, resembling low cranberries, and sometimes substituted for them.

Flower clusters have inner fertile flowers, outer sterile ones. They remain on the bush after the leaves have fallen and throughout the winter. The bark has no smell, but has a peculiar bitterish and astringent taste, which leaves a clean taste in the mouth. Viburnine is the active principle found in the dried bark of the stem.
