Cultivation: It is easy to grow.  It  prefers a neutral to slightly acidic mineral-based potting mix with plenty of extra grit and feed during the summer.   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 kept dry  (rots easily if soil is wet and cold) tends to lose its roots in winter. Water Best if watered with rain water. Usually it is recommended to over-winter this plant in a bright and warm greenhouse with at least 8-10° C and rather dry  (it tends to lose its roots and to rot  if the substrate is wet and cold)  but it has proved to tolerate temperatures as low as -5° C for short periods.

Seeds.
