This native perennial plant is 2½4' tall, branching frequently in the upper half. The light green stems are four-angled and hairless. The opposite leaves are broadly lanceolate to ovate, and vary in color from light green to dark green, sometimes with yellow or red tints. These color variations are in part a response to environmental conditions. The hairless leaves are up to 4" long and 2" across, and have serrated margins. They exude an oregano scent. At the top of major stems are rounded heads of flowers about 1-3" across. The flowers begin blooming in the center of the head, gradually moving toward its periphery, forming a wreath of flowers. Each flower is lavender or pink, and about 1" long, with an irregular shape. The corolla divides into a tubular upper lip with projecting stamens, and three slender lower lips that function as landing pads for visiting insects. The blooming period occurs during mid-summer and lasts about 1 month. The root system consists of deep, strongly branched roots, and shallow rhizomes that are responsible for the vegetative spread of the plant. These rhizomes typically send up multiple leafy stems in a tight cluster, giving Wild Bergamot a bushy appearance.
