It is a herbaceous perennial with glabrous stems 10–100 cm long that bear terminal or axillary racemes or spikes of soft violet flowers. The leaves are 1.5–8 cm long and 3 to 20 times as long as wide, short-petiolate, glabrous, serrate to almost entire.[3] The plant can be confused with Scutellaria (skullcap) and other members of the mint family.
