Winter hardy to USDA Zones 10-11 where plants are best grown in well-drained soils in full sun to part shade. Must have sharply-drained soils. Allow soils to dry out after each watering, but water consistently in summer as needed to prevent soils from totally drying out. Decrease watering in winter. Plants are intolerant of frost. Potted plants may be overwintered indoors. May be grown as a houseplant.
