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.

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.
