Conophytum calculus - 20 seeds
Conophytum calculus - marble buttons - is a small, but very tough, low growing, stemless succulent with individual rounded “leaves” (fused together into one body) that multiply with age and cluster together to form a dome-shaped cushion. The spherically-shaped leaf bodies are completely smooth and hairless, characteristically opaque (non-transparent and non-glossy) and have a chalky-green to pale yellowish green color. The leaf bodies are always without any spot or detail and up to 1.2 inches (3 cm) in diameter. New leaves are formed inside the existing ones and when, after a year, the leaf body starts to die, a new one emerges from inside. The old leaf becomes a thin, dry, and smooth, beige colored sheath, sometimes turning black, which persists on the plant. It flowers in autumn and has spicy, clove-scented, golden yellow to dark orange flowers which are nocturnal. They only open at night.
