Pleiospilos nelii - Cacti and Succulents

Pleiospilos nelii

Split Rock, Cleft Stone, Mimicry Plant

The plant blooms in the mid-afternoon and closes its petals by dusk. The flowers will repeat this pattern for a few days and then they will start to dry up and if pollinated, will make a seed pod.


I water only in the spring and early fall when the temperature starts to drop and the days get shorter. Allow the soil to dry completely between waterings (see below for info on soil). Hold back water during the hottest weeks of summer and also in the dead of winter. If the old leaves are still present at the end of summer, it may be getting too much water. If the plant rots and dies, it may be getting too much water.

IF YOU JUST TRANSPLANTED YOUR SPLIT ROCK YOU MUST WAIT A WEEK AND THEN WATER – IT DOESN’T MATTER WHAT TIME OF YEAR OR HOW MANY LEAVES IT HAS! If you don’t it will just sit there and not do anything. You must encourage it to grow new roots. After the first week’s watering, wait until the soil is fully dry then water again. Wait yet another week and give it a tug. If it feels established in its new home, continue to water as you normally would for that particular time of year.


Propagation of Pleiospilos nelii

All you have to do is cut off a leaf from the parent plant in spring just before your split rock has brought out any new growths. And the rules as far as cutting tools are concerned still hold – should be sharp and sterilized.

Allow the cut part to callous before placing the leaf in a well-draining mix to root.
