Winter hardy to USDA Zones 10-11. In zones 5 and lower , it is perhaps best grown as an annual vine that is replaced each spring. Grow in organically rich, fertile, medium moisture, well-drained soils in full sun to part shade. Best with some afternoon shade. Easily grown from seed sown directly in the garden after last frost date. Start seed indoors 6-8 weeks before last frost date for earlier bloom. Also may be grown in containers that can be overwintered indoors in a warm sun room. Cuttings may be taken from favorite plants in late summer for overwintering.
