50 SEEDS RARE LITHOPS OPTICA RUBRA (Mesembs exotic succulent living stones cactus)

Lithops is a genus of succulent plants native to southern Africa. "Lithos" means "stone" and "-ops" means "face" in Ancient Greek; therefore "Lithops" means "stone-like". This is a very good description of these plants, which avoid being eaten by blending in with surrounding rocks. They are often known as pebble plants or living stones. The formation of the name from the greek "-ops" means that even a single plant is called a Lithops.
Rainfall in Lithops habitats ranges from approximately 700mm/year to near zero. Rainfall patterns range from exclusively summer rain to exclusively winter rain, with a few species relying almost entirely on dew formation for moisture. Temperatures are usually hot in summer and cool to cold in winter, but one species is found right at the coast with very moderate temperatures year-round.
Lithops thrive best in a coarse, well-drained substrate. Any soil that retains too much water will cause the plants to burst their skins as they over-expand. Plants grown in strong light will develop hard strongly colored skins that are resistant to damage and rot, although persistent overwatering will still be fatal. Excessive heat will kill potted plants as they cannot cool themselves by transpiration and rely on staying buried in cool soil below the surface.
