|Resembles M.didyma. Bushy and upright growth pattern, with the square stems of the mint family and pungent, oregano-scented foliage. The flowers are clustered at the top of the stem, each tiny flower having the two-lipped pattern of mints.
They attract bees and hummingbirds.
Easy to grow from seed, or by division. Site them mid border, as they can look untidy after flowering. Good for the cottage garden look. They prefer moist well drained soil, and can get powdery mildew, so give them good air circulation. Native from the eastern U.S. to the Rocky Mountains.
