Though several species of mountain mint (Pycnanthemum) grow naturally in the meadows here at Hayefield, I can’t resist trying other kinds of this marvelously minty genus. Hairy mountain mint (Pycnanthemum verticillatum var. pilosum) flowered the first time for me in 2020. Overall, its look is somewhere between P. virginianum and P. tenuifolium, with upright, fuzzy stems reaching 3 to 4 feet tall that carry relatively narrow, hairy leaves and clusters of small, purple-dotted white flowers in summer. Like other mountain mints, it is popular with a wide variety of bees, butterflies, and other pollinators, and it is marvelous as a cut flower, though perhaps not as fragrant as the other species. The plants spread by rhizomes, so they’re best grown in a meadow-type garden or naturalistic planting rather than a formal border.
Hairy mountain mint is native to the eastern half of North America. Full sun; average to moist soil. Perennial; Zones 4 to 8.
Collected in October 2020. At least 30 seeds.
