Winter hardy to USDA Zones 9-11 where it is best grown in loose, humusy, evenly moist but well-drained soil in full sun to part shade. If climbing is desired, tie stems to a support. Prune as needed to maintain plant shape. Propagate from cuttings in summer. In St. Louis, plants may be purchased in spring in containers. Container plants may be brought inside before first fall frost for overwintering in bright sunny rooms of moderate temperature with reduced watering.
