Virginia Mountain Mint

This is a perennial herbaceous plant up to 3' tall and branching frequently, often with a bushy appearance. The green or reddish stems are strongly four-angled and have scattered white hairs along the ridges. The opposite leaves are up to 2½" long and narrowly lanceolate or linear. They are sessile, and have smooth margins. The largest leaves are ¼ - ½" across. When damaged, the foliage releases a strong mint scent.

Numerous flattened heads of small white flowers (often with purple dots) occur at the ends of the upper stems. Each head is up to ¾" across and can contain up to 50 flowers. However, only a few of these are in bloom at the same time, beginning with the outer circle of flowers and ending towards the center. Each tubular flower is about 1/8" long and 2-lipped. The blooming period occurs during the middle of summer and lasts about a month. Each small flower produces 4 tiny, finely pitted, dull black seeds. These seeds are distributed to some extent by the wind. The root system produces rhizomes, which spread a short distance from the mother plant. Soon, a small colony of plants are formed vegetatively.
