Una piccolissima succulenta sudafricana (Aizoaceae) consistente in un paio di foglie fuse e a forma di ciottolo con una fessura da cui emerge il fiore.
Very bright light with several hours of direct sun is essential to keep these 'living stones' compact; insufficient light causes them to elongate and lose their stone-like form and markings.
Extremely seasonal and easy to kill by overwatering. Water lightly in autumn (flowering) and spring (new body); keep COMPLETELY dry in winter and during summer dormancy while the old body absorbs into the new pair of leaves.
Very gritty, almost entirely mineral mix with extremely sharp drainage.
Warm in growth 18–30 °C; cool, dry winter rest around 10 °C. Low humidity.
Generally none; at most a very dilute low-nitrogen feed once in autumn. Excess nitrogen, not feeding as such, is what causes the bodies to burst — so avoid high-nitrogen fertilizers.
None — let the old leaves dry to papery sheaths and absorb naturally; never pull them off early. Non-toxic.
