Cultivation:
This is an easy plant to cultivate. It likes to be kept cool, and
needs only a short rest in winter. It can can tolerate light frost.
Grow in full sun or light shade, but it doesn't like full, hot blazing
sun in the central summer months. 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. It 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.
