Blue vervain (Verbena hastata)

Blue vervain (Verbena hastata) typically flourishes in wet habitats such as stream banks, marsh edges, and damp meadows across the United States and Canada. It serves as a magnet for pollinators like bees and butterflies, and birds, including finches and sparrows, are drawn to its seeds. Additionally, Common Buckeye caterpillars use it as a host plant. While traditionally utilized in various cultural medicinal practices, modern research has identified some potential adverse effects on human health under certain conditions.
