Also known as American Blue Vervain and Swamp Verbena. Grows upright 3-5’ tall, yet also is creeping, with multiple spikes of long-lasting bright blue/purple flowers that bloom from June through September. This self-seeding herbaceous perennial is native to the Eastern US. The leaves and roots were traditionally used as medicine, dried or fresh. Leaves were used in a boiled tea as a spring tonic, and roots were used for colds, fevers, indigestion, an antidote to American Pokeweed poisoning, and many more ailments. It’s a great pioneer species on degraded land, a larval host for pollinators, and helps to stabilize streambanks. Also used in landscaping for its lovely bright flowers. Tags: Color: Purple, Season: Spring Summer Fall.
