        |  | Cultivation:
        This is an easy plant to cultivate. 
        It likes to be kept cool and need only a short rest in winter, it 
        can can tolerate light frost. Grow in full or light shade sun
        but doesn't like full, hot blazing sun in the central 
        summer month. Water occasionally in winter so the roots do not 
        dry out completely and water regularly in summer. Some growers suggest 
        to use exclusively rain water. But be careful as it will rot easily if 
        the substrate is wet and cold. Tends to lose its roots in winter. The root system of this plant is comparatively small and it is best to 
        grow it in a shallow pot using a neutral to slightly acidic compost with 
        plenty of extra grit. Give an occasional tonic of sequestrated iron.
 Reproduction:  Usually by seeds as it 
        seldom produces offsets.  |
