Propagation Technique

Best from fresh seed which is slow to germinate. Semi-hardwood cuttings will strike but they can be slow and results variable. Best strikes have been achieved when cuttings have been placed in untreated saw dust. An attractive plant for a small garden, prefers full sun, and nutrient poor soils, resents competition, and is prone to phytophora and verticillium wilt


Not Threatened
