Tender perennial is winter hardy to USDA Zones 7-10. In colder zones, grow as an annual in average, moist, well-drained soils in full sun to part shade. Plants freely self-seed and naturalize in gardens throughout perennial plantings. A wonderful pollinator nectar food and cut flower for arrangements!
Host plant for Common Buckeye butterflies. One of the best flowers for butterflies and hummingbirds.
