Split Rock is a member of the Pleiospilos family. Its botanical name is Pleiospilos nelii.
The body of the plant consists of a pair of leaves, fused at the base, usually grey green to brownish in colour, (but in the case of the above variety an attractive wine colour) with darker markings scattered over the whole of the leaves. The plant produces a new body from within the old one each year, much the same as Lithops and Conophytums do.A type of succulent, it mainly grows as a perennial plant - which means it typically grows best over a long period (from 3 years+). Keep in mind when planning your garden that Split Rock is known for growing to a stemless habit.
South Africa is believed to be where Split Rock originates from.

I would suggest that they should be grown ‘hard’. By this I mean do not over water and do not over fertilise. If either of these are done to excess, apart from risking the plant dying, it will start to [stack]. This is the term that is used when there are more than 2 pairs of leaves showing at a time. If the plants are grown correctly, ideally there should only ever be 2 pairs of leaves. The lower ones are the previous years, and the top ones, the current years These top leaves are using the lower ones as a food source. The lower leaves will be drained of all their goodness and end up as a parchment like skin, which when totally dry can be carefully removed. As you can see my own plant has ‘stacked’ a little. The remains of the body from two years ago is still slightly in evidence.
