Living stones, Stone plant
Lithops turbiniformis (Living stones). The plants will form small clumps of paired leaves. They are egg-shaped and orange-brown in colour, they will grow about 25mm.
These frost-tender succulents are easy to grow but require very dry conditions, so need to be kept under shelter in all but arid climates. Plant in coarse, gritty soil and allow full sun. Water only in spring.
