Cultivation and Propagation: It is easy to grow. It prefers a neutral to slightly acidic mineral-based potting mix with a good drainage. It likes a warm bright location, does great in partial shade but doesn't like full, hot blazing sun in the central summer month. Can support quite some water during the growing season but pot plants in winter are wet-sensitive and needs to be rather kept dry (rots easily if soil is wet and cold) tends to lose its roots in winter. Usually it is recommended to over-winter this plant in a bright and warm greenhouse with at least 8-10° C , but it has proved to tolerate temperatures as low as -5° C for short periods.
Propagation: Seeds, cuttings or root suckers (if available). Not too difficult to raise from seed.
