Verbena - Vervain
Verbena is a genus of about 250 annual and perennial species native to the Americas. Two are native to Europe and the Mediterranean region. The name means "sacred foliage", and one of the Old World species, Common Verbena (Verbena officinalis), is most fabled. Common Verbena, aka Vervain, is now widely naturalized elsewhere. Its potent medicinal properties undoubtedly led to its association with the supernatural.
Growth height varies. Low-profile species are excellent for ground cover, rock gardens, container gardens, hanging baskets and terraces. Taller species are excellent for perennial gardens, cutting and flower-arranging. Verbena attracts butterflies, too.
