Blue vervain typically features tall, erect stems that can reach heights of 2 to 5 feet (60 to 150 cm). The stems are often square-shaped and bear lance-shaped leaves with serrated edges. Throughout the blooming season, small, tubular, violet-blue flowers cluster in elongated spikes at the top of each stem. The inflorescences give off a delicate appearance, contrasting with the plant's robust structure. Spirally arranged on the spike, each flower has five petals that are fused at the base, creating a flared mouth.
