Skullcap is an attractive, easy-to-grow perennial suitable for the home landscape.  A member of the Mint family.  Named for the cap shape of the flower and also for seed capsules that slightly resemble helmets worn by military during the Middle Ages.  Typically native to wetter ground such as wet pine savannas, seeps in forests, bottomlands, low meadows and other moist sites.  However once established can be fairly drought tolerant and is occasionally found in non-wetland areas.  Does not attract a lot of pollinators but is bitter tasting and slightly toxic to deer and rabbits.
