About
Verbena officinalis, the common vervain or common verbena, is a perennial herb native to Europe.
Where it grows
The plant is native to Europe but is widely naturalised outside its native range, for example in North America. It prefers limey soils.
Uses
Common vervain has been held in high esteem since classical antiquity; it has long been associated with divine and other supernatural forces, and it has an equally long-standing use as a medicinal plant. Herbal capsules are used as a soporific drug in much the same way as for the better known valerian.
