Winter hardy to USDA Zones 10-11 where it is easily grown in average, medium, well-drained soils in full sun. Tolerates part shade, but best flowering in full sun. Best in organically rich, fertile soils. In colder zones, grow in the ground as bedding annuals that are replaced in the garden each spring or in pots/containers as frost-tender perennials that are overwintered indoors. May be easily grown from seed started indoors in late winter approximately 8-10 weeks before last frost date. During the growing season, water regularly (allow soils to dry somewhat between waterings) and feed monthly. To overwinter, bring pots/containers inside before first frost to a bright, cool (50s) location and reduce watering.
