Tender perennial that is winter hardy to USDA Zones 7-10. In St. Louis, it is grown as an annual. Start seed indoors 10-15 weeks before last frost date. Starter plants are generally available for purchase in cell/six packs from a variety of retail outlets. Set seedlings/starter plants out at last frost date. Easily grown in average, evenly moist, well-drained soils in full sun to part shade. Tolerates full shade, but foliage color is best with some sun. Gardeners usually remove flower buds as they appear. Shear plants back if they become leggy. Cuttings may be taken in fall for overwintering, but most gardeners simply repurchase new plants in spring.
