Pycnanthemum virginianum (L.) T. Dur. & B.D. Jacks. ex B.L. Rob. & Fernald
Virginia Mountain Mint
Lamiaceae (Mint Family)
Synonym(s): Koellia virginiana
USDA Symbol: pyvi
Virginia mountain-mint is a stout perennial, becoming multi-branched toward top of its 2-3 ft. height. Tiny, white, mint-like flowers, often spotted with purple, are arranged in numerous small, dense clusters. The clusters, which bloom only a few at a time, arise from leaf axils at the stem tips. The foliage of this leafy plant is covered with a whitish bloom.
Virginia Mountain Mint is a member of the family Lamiaceae which includes aromatic herbs or shrubs, rarely trees or vines, usually with stems square in cross-section, 4-sided, and flowers in long clusters, heads, or interrupted whorls on the stem. There are about 180 genera and 3,500 species nearly worldwide. The Mediterranean region, the chief area of diversity, has produced many spices and flavorings; various mints, oregano, marjoram, thyme, sage, and basil. Catnip and lavender are in the family.
