Blooms April-October. Creates a lush groundcover. Snake Herb is a multi-branched perennial. The square stems are covered with stiff hairs. Lavender to purple flowers are 2-lipped with a purple stripe running down the throat. Blooms mainly in Spring but will also do so throughout the year after a rain. Attracts butterflies.
