CommentsThis is another member of the Mint family with pairs of opposite leaves and relatively small tubular flowers. Hairy Wood Mint (Blephilia hirsuta) has unusually hairy stems and the dense hairy whorls of flowers are rather conspicuous. These dense whorls of flowers distinguish the genus Blephilia from many other members of the Mint family. The only other member of this genus that occurs in Illinois is Downy Wood Mint (Blephilia ciliata). Downy Wood Mint has leaves that are sessile or they have short petioles (less than ½"), and its stems are short-pubescent to pubescent. Hairy Wood Mint, on the other hand, has leaves with longer petioles and its stems have spreading white hairs that are quite long. Downy Wood Mint prefers habitats that are somewhat sunnier and drier; it is sometimes found in prairies and savannas.
