Growing

Verbena bonariensis prefers full sun and well-drained soil. Regular, moderate watering is important; avoid waterlogging. The plant is easily propagated from seed or cuttings. To encourage bushier growth, cut back in early summer. It is hardy in USDA zones 7 to 11; in colder regions grow it as an annual.
