''Scutellaria lateriflora'', also known as Blue Skullcap, Hoodwort, Virginian Skullcap, Mad-dog Skullcap is a hardy perennial herb native to North America. It is a member of the mint family. It has an upright habit, growing 60 to 80 centimeters in maximum height. It is a wetland-loving species and grows near marshes, meadows, and other wet habitat. The blue flowers are just under a centimeter long. Most of the flowers do not appear at the top of the main stem, but are produced along the length of side branches that grow from the leaf axils.
