Habitat and range.—The balm-of-Gilead tree, which has mostly escaped from cultivation, is found along roadsides or streams from Newfoundland to Minnesota and Georgia.
Description.—This is a large tree reaching a height of 100 feet with a maximum trunk diameter of about 6 1/2 feet with spreading branches, the young twigs slightly hairy, and with very resinous, fragrant buds. The broad, pointed leaves, 2 1/2 to 6 inches long, are somewhat heart-shaped at the base, fine toothed, dark green above, pale beneath, and hairy when young. The male and female flowers are borne in separate catkins 6 inches or less in length, which appear before the leaves.
Part used.—The leaf buds.
