Description from Prairie Moon Nursery: Mountain Mint attracts many insects to its flowers, including various bees, wasps, flies, small butterflies, and beetles. The leaves are very fragrant; when crushed they have a strong minty odor. The flowers will be white to shades of light purple, some with purple spots. Pycnanthemum means “densely flowered,” an attribute that enables Mountain Mint to accommodate many pollinators at once. The long bloom time, a month or more in July and August, is another reason Mountain Mint is a great choice for those interested in feeding pollinators. The light green foliage of all Mountain Mint species is visually pleasing, too, making it a nice garden choice even when not flowering.
For a shorter species, in medium soils, try Slender Mountain Mint. Other common names are Mountain Thyme, Pennyroyal, and Prairie Hyssop.
