Slender mountain mint typically grows to a height of 2 to 3 feet. Its small, white flowers, often dotted with purple spots, are about 1/4 inch long and bloom in dense, terminal clusters. The leaves are very narrow and almost needle-like, up to 3 inches long and about 1/4 inch wide. They are opposite, linear, and hairless, with a prominent central vein and smooth margins. This plant is quite adaptable and can be found in a variety of habitats, including dry, open rocky woods, dry prairies, fields, along roadsides, stream sides, and in open, wet thickets. It prefers full sun to part shade and can thrive in dry to medium soil conditions. (SF)
