Mountain Mint is an erect, multibranched native whose square stems develop dense, flat-topped flower clusters at their tips. The blooms are white, often flecked with purple, and cover the plant for a month or longer in mid to late summer. They act as a magnet to insects of all kinds such that it is rare to see Pycnanthemum in bloom and not absolutely abuzz with pollinators. Its narrow, opposite leaves give off a strong minty aroma, can be used to make tea and can also be rubbed against the skin for a natural mosquito repellant. While not as aggressive as many other mints, this species is a vigorous grower and should be planted alongside other stalwart plants that will not cede their ground. Can limit its spread by pruning the roots or pulling unwanted new shoots in the spring. Hardy and drought tolerant once established. Unpalatable to deer and rabbits.
