Mountain Mint

Pycnanthemum muticum
A cloud of dense green leaves dusted with powdered sugar, or so it seems, for this spearmint-scented mint family member develops a multitude of silvery-white bracts surrounding tiny clusters of pale flowers in summer. Easily grown in rich, regular to moist, well-drained soils, it spreads to make good clumps but is not invasive—a top-ten pollinator plant.

PLACEMENT & CULTIVATION
Mountain mint attracts a wide array of pollinators, providing nesting sites and abundant nectar and pollen resources over its extended summer bloom period. A valuable, deer-resistant addition to rain gardens, meadow gardens, as well as dry, sunny banks and seaside gardens, blooming best in full sun. While it spreads through rhizomes, it is not invasive. If desired, pruning the roots in spring with a spade can help prevent excessive spreading. Fragrant mountain mint is a top choice for attracting beneficial insects, supporting their thriving populations, and contributing to a healthier ecosystem.
