This aromatic perennial grows 1 to 4 ft high and has branched, hairy stems. The opposite leaves are distinctly petioled and slightly toothed. Wild bergamot has square stems with gray-green foliage. The flowers bloom from June to September. The flowers are tubular with lobes much shorter than the tube.
Bergamot is listed as an ingredient in Earl Grey tea, but this is actually the oil from the bergamot orange. Many Native American groups used this member of the mint family for medicinal purposes, and some people still drink bergamot tea during cold and flu season. This plant is also the source of the antiseptic Thymol, used in some mouthwashes.
