Mad Dog Skullcap is a native mint-family wildflower of moist woodlands and stream banks across eastern North America, producing small, blue to lavender two-lipped flowers along one-sided racemes from the leaf axils in summer. Growing 1–2.5 feet tall, it was historically used as a remedy for rabies (hence 'mad dog') and as a nervine for anxiety — uses still popular in herbal medicine. The genus name refers to a small cap-like projection on the flower calyx.
