Plant Profile: Pycnanthemum tenuifolium

Mountain Mint is a perennial wildflower indigenous to various habitats, including dry meadows, fields, thickets, open woodlands, upland prairies, and along roadsides, as well as in well-drained Post Oak forests and pine barrens. This plant typically exhibits a stiff, upright, and compact growth habit, reaching heights of around 2 feet, though it can occasionally grow up to 4 feet tall. Blooming occurs once the plant achieves a width of about 1 foot, and all parts of Mountain Mint emit a minty fragrance when crushed.

The flowers consist of clusters of small, two-lipped corollas that vary in color from whitish to lavender, often adorned with purple spots.

Mountain Mint is ideal for naturalizing in gardens or for use in rain gardens. It has a tendency to spread vigorously, so it is advisable to provide ample space or to prune it as necessary.

The dried leaves can be used to brew tea, and when rubbed on the skin, they act as a natural mosquito repellent.

This plant is a magnet for native bees, bumblebees, and honey bees.

In 2019, Mountain Mint was honored as the NC Wildflower of the Year, a recognition facilitated by the North Carolina Botanical Garden with support from the Garden Club of North Carolina.

In terms of pests and diseases, Mountain Mint does not face any significant challenges.
