Mad-dog Skullcap is a mint-family perennial plant with toothed, opposite leaves and a square stem, which is typically hairless. It blooms small, trumpet-shaped flowers, varying in color from pale blue to lavender or even white, from July through September. The flowers attract native bees. This lovely plant thrives in wet-to-moist conditions and is rhizomatous but not aggressively so. The common name of “skullcap” is a reference to the cap shape of the flower and seed capsules, which slightly resemble helmets worn by military during the Middle Ages. "Mad-dog" is a reference to the belief that this plant had properties that could cure rabies, which has been disproven.
