A northern species native in rocky openings on Isle Royale and some other sites in the western Upper Peninsula and in the jack pine plains, but also finding suitable habitat in the fields, roadsides, and other disturbed ground generated by settlement elsewhere in Michigan.

The spiny floral bracts and calyx lobes, with nearly concealed flowers, give the heads a forbidding appearance. The calyx lobes have prominent cross-veins between the nerves in this genus, unlike Nepeta, which has no evident cross-veins on its small calyx.
