Pycnanthemum muticum

Silvery bracts highlight dense clusters of small whitish flowers from summer to early fall. The flowers are an extraordinarily good source of nectar for smaller types of butterflies. The leaves smell strongly of spearmint when they are crushed. Mountain Mint is loaded with pulegone, the same insect repellent found in pennyroyal. It can be rubbed on the skin to repel mosquitoes!
