Pycnanthemum muticum

Short Toothed Mountain Mint

<< PREV Image 1 of 2 NEXT >>

Silvery bracts highlight dense clusters of small pinkish 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 and, like many members of the mint family, the leaves may be used in teas.

Vigorous, easy-to-grow plant that thrives in a wide variety of conditions

Native Trivia

Beneficial insects such as ladybugs, lacewings and other insects feed on troublesome insects in the garden. To get energy to search for their prey, many beneficial insects feed on nectar (for carbohydrates) and pollen (for protein) from flowering plants.

Mountain Mint is loaded with pulegone, the same insect repellent found in pennyroyal. It can be rubbed on the skin to repel mosquitoes!


"This is the best nectar plant around, with a very long bloom time, so we butterflies visit the flowers often."
