In the Leslie Hill Stone Plant House you can see some of the most peculiar dwarf succulent plants in the world. The display represents a transect through South Africa, from the west coast desert to the east coast of the Eastern Cape. The middle beam of the plant house divides the winter and the summer rainfall flora. In the north-east corner you will see (or not!) succulents with camouflaging features such as Lithops, Conophytum, Euphorbia, Fockea, and Gasteria, along with rocks and soil from each region.
In the display are two species discovered by Leslie Hill, a succulent plant enthusiast and collector: Astridia hallii and a Lithops. As most of the plants with camouflage come from quartz gravel flats, this corner unit is based on the Knersvlakte. The name comes from the grinding ("kners" in Afrikaans) sound of ones footsteps on the stones and part of the floor is specially covered with quartz gravel for a hands on (feet on?) experience of the Knersvlakte. The gravel was especially collected from Oom Buys Wiese's farm Kwaggaskop.
Rocks from the various regions were introduced as well. These include Enon conglomerate, Beaufort- & Malmesbury shale, dolomite, surface limestone, limestone nodules, Dwyka Tillite, Quartz, Gneiss & Malmesbury shale.
