Where it grows
The ‘split rock’ plant is native to the Great Karoo region of South Africa.
Special features
Pleiospilos nelii is one of the most popular succulents in the hobby due to its appearance. It resembles stones that occur in its natural habitat, which is an adaptation called ‘mimicry’, which it used to avoid being eaten by herbivores. It is gray with small black spots, and oval in shape with a split down the middle where new growth occurs. Produces yellow or orange flowers in late winter.
Care Guide
This species prefers lots of light and should be kept in a sunny spot in the greenhouse, or in an area that receives morning sun. Plant it in a well-draining, sandy soil mix that does not stay wet for more than a 2-3 days. Pleiospilos nelii can be watered throughout the year, but only once per month. Drench the soil and let it dry for 3-4 weeks before watering again, rather than giving it small amounts of water more frequently. It is important to water this species in winter, otherwise it will not flower.
