Keep just moist in winter and maintain low to moderate humidity. Can be grown outdoors in frost-free areas in moderately fertile, humus-rich, moist-but-well-drained soil. Protect form cold, drying winds and excessive winter wet

Propagation Propagate by seed sown in containers in a cold frame in spring or root softwood cuttings in spring or early summer. Semi-hardwood cuttings can be taken in late summer or autumn, with bottom heat
