Argentine vervain is a tall, airy perennial that produces clusters of small purple flowers beloved by pollinators from summer through autumn. Plant it in full sun with well-draining soil and water regularly until established, after which it tolerates short dry spells well. It self-seeds readily, making it an effortless naturalizer in cottage and wildlife gardens.
