Description

Mountain Mint is a native wildflower and herb that attracts many bees and butterflies with its wonderful minty smell and abundant nectar. Its native habitat is dry to wet thin woodlands, thickets and meadows. The densely packed heads have many small flowers that bloom from about June to August. It grows 3- 6 feet tall and about 2 feet wide.

Mountain Mint is easy to grow in average to dry soils in full sun to partial shade. Use in a pollinator garden or naturalized area.
