The name 'Mountain Mint' is something of a misnomer, because this plant and the majority of other members in this genus do not usually occur in mountainous habitats. Common Mountain Mint is similar in appearance to Pycnanthemum tenuifolium (Slender Mountain Mint). It can be distinguished from the latter species by the white hairs along the ridges of its stems, and the occurrence of leaves greater than ¼" across. Another difference is the presence of a strong mint fragrance in the crushed leaves of Common Mountain Mint, while the leaves of Slender Mountain Mint usually have a milder scent. Return
