Looking for a hardy and drought-resistant plant for your garden or landscape? Consider Verbena hastata, also known as American vervain, blue vervain, or swamp verbena. This common plant grows across North America and features opposite, simple leaves with double-serrated margins on stiff, erect stems. In summer, you'll enjoy purple flowers that attract bees and other pollinators. This species is a member of the diploid North American vervains and is hybridized with other related species. Despite often being considered a weed, blue vervain is valued for its medicinal properties and adaptability to different habitats, making it a versatile addition to your outdoor space.
