Description
Likely native to the Mediterranean region, vervain grows wild throughout much of Europe and North Africa, as well as in China and Japan. It is a slender perennial, growing to three feet with stiff, thin stems and spikes of small lilac flowers. The American Blue Vervain (V. hastata) is a perennial native to the northern US and Canada. The plant grows up to five feet in height and produces blue flowers, hence its name. American varieties are found mainly on moist prairies and meadows, low open woodlands, stream banks, and around springs, seepage areas, and roadsides. The aerial parts are gathered in the spring and summer while flowering.
