Pot plants are quite wet-sensitive. Care must be taken with watering; it needs good drainage. Water sparingly during the growing season, and keep very dry in winter.
Usually it is recommended to overwinter this plant in a bright and warm greenhouse with at least 8-10° C , but it has proved to be quite frost resistant ( -5° C). Give top shelf treatment. (Full sun - Light shade) Propagation: Seeds, cuttings or grafting. |
