Mountain Mint (Pycnanthemum incanum) is a perennial herb that grows 3-6 feet in height. It is minty smelling and has stiff, four-sided stems with terminal flowers. This plant is easy to grow- it likes full sun to partial shade, low to medium water usage, and a wide variety of soils. Its leaves are an attractive silvery color and are more ornamentally valued than the flowers, which are small, white to lavender purple-spotted, clustered around the top of the plant, and bloom in June and July. Mountain Mint is benefecial in that its fragrant foliage attracts butterflies, bumblebees, honeybees, and other pollinators.
