Narrow-leaf Mountain Mint Pycnanthemum tenuifolium

Phonetic Spelling
pik-NAN-thee-mum ten-yoo-ih-FOH-lee-um
Description

Mountain Mint is a native perennial wildflower found in dry meadows, fields, thickets, open woods, upland prairies, along roadsides as well as fast-draining Post Oak woods and pine barrens.  Its clumping form is stiff, erect, and compact.  Typically growing to a height of 2', it can grow larger, up to 4'.  It will begin blooming when the plant reaches a width of approximately 1' wide.  All parts of the plant have a minty aroma when crushed.

The flowers are clusters of many small, two-lipped corollas ranging from whitish to lavender with purple spots.

This plant is good for naturalizing or in a rain garden.  It can spread aggressively, so it benefits from having space or being cut back as needed.

The dried leaves are used in making teas. Rub the leaves on your skin to serve as a mosquito repellent.  

Attracts native bees, bumblebees and honey bees.  

Insects, Diseases, and Other Plant Problems:  No serious issues.
