About Pycnanthemum virginianum (L.) T.Durand & B.D.Jacks. ex B.L.Rob. & Fernald
Pycnanthemum virginianum, commonly known as Virginia mountain-mint or common mountain-mint, is a herbaceous species in the mint family, Lamiaceae. It grows on wiry green stems, producing narrow, simple leaves that grow in opposite arrangements. In summer, it bears white flowers marked with purplish spotting. Like most species in the Pycnanthemum genus, its foliage releases a strong mint fragrance when crushed or disturbed. This plant is native to eastern Canada and the eastern United States. A wide range of insects visit its flowers, including honeybees, cuckoo bees, sweat bees, thread-waisted wasps, potter wasps, tachinid flies, wedge-shaped beetles, and pearl crescent butterflies.
