About

Pycnanthemum muticum, commonly known as clustered mountain mint, is a plant from the genus Pycnanthemum that is native to the eastern United States. It grows in well-watered dappled woodlands and meadows in the wild. It is also planted in gardens because it is highly attractive to butterflies and other pollinators.

How to grow it

Clustered mountain mint is sometimes grown in gardens, particularly ones emphasizing native plants or to benefit pollinators. Many different kinds of insects are attracted to the strong nectar flow including bees, wasps, moths, and butterflies.

They are more valued for the silver colored bracts which last much longer than the blooms. The seedheads dry out and persist over the winter, providing light cover and nesting material to birds.

Where it grows

This species is found in scattered locations from Florida to Maine on the east coast of the United States and as far west as Texas and Michigan. It is most common in the eastern US in the Appalachian Mountains, in the eastern half of Pennsylvania, New Jersey, Connecticut, Massachusetts, Vermont, and New Hampshire. To the west, it is also quite common in Arkansas and Louisiana.
