Hairy Mountain Mint

Hairy Mountain Mint (Pycnanthemum pilosum)

Hairy Mountain Mint (Pycnanthemum pilosum) is a robust, native perennial prized for its aromatic, hairy foliage and clusters of small, white flowers. This late-summer bloomer adds soft color, rugged texture, and an ecological focal point to native gardens, meadows, and pollinator-friendly landscapes.

Distinctive Features

'Hairy Mountain Mint' forms upright, branching clumps of green foliage covered in fine, soft hairs that give the plant a silvery appearance. From mid to late summer, clusters of tiny, nectar-rich white flowers bloom at the tops of the stems, attracting a wide array of pollinators, including bees, butterflies, and beneficial insects. The foliage releases a strong, minty fragrance when crushed, adding sensory interest to the garden. Its dense, clumping habit makes it an effective natural ground cover, and its resilience adds to its appeal in low-maintenance landscapes.
