Verbena hastata, also known as Blue Vervain, is a perennial wildflower native to Michigan and the UP. Blue vervain reaches 3 to 5 feet tall and flowers from July to September with a candelabra of blue blossoms. It is naturally found in wetlands or near streams and lakes, and prefers full sun to partial shade, medium to wet soil, growing in muck, clay, loam or sand. With a touch of water during drought, it is just fine as a garden plant in regular soil. This short-lived perennial spreads slowly by rhizome and may reseed in ideal conditions. It has a long bloom time, making it popular with pollinators.
