Hoary Mountain Mint is a clumping native perennial with dense branching stems covered with dark green toothed foliage with grayish-white undersides and emit a strong spear-mint aroma if crushed. The axillary clusters of tiny two-lipped white to lavender flowers surrounded by hoary silvery upper leaves and brackets bloom throughout summer. Best flowering occurs in full sun and medium to dry well-drained soils.
Pycnanthemum incanum is a host plant for the Wavy-lined Emerald Moth and is extremely popular as a nectar source for many butterflies, bees, moths, and beneficial parasitical wasps. A great plant for increasing the number and variety of pollinators to the garden.
