Blephilia, the pagoda plant or wood mint, is a genus of four species of flowering plants in the family Lamiaceae. They are all herbaceous plants native to eastern North America.[1][2] Blephilia are most often found in open areas, glades, and mesic forests. All species of Blephilia are considered threatened or endangered in some states.[3][4][5] [6]
The genus includes only perennial species that spread by both seeds and through stem division. Small white to purple-lavender flowers occur in inflorescences that cluster in the upper leaf axils, often in several circular layers (hence the common name pagoda-plant). Leaves are generally lanceolate to ovate and vary in shades of green. Leaves are either petiolate or subsessile (depending on the species).[5] Like many other members of the subtribe Menthinae, all parts of Blephilia are highly aromatic when crushed and have smells similar to menthol and spearmint.[citation needed]
