'Living rock' is another common name for *Pleiospilos* succulents, known for their resemblance to stones. These plants have evolved to mimic the colors and textures of rocks, blending seamlessly into their environment. Unlike most plants, they have very few leaves and a compact shape. Think of them as nature's optical illusion. This adaptation protects them from herbivores and harsh sunlight. They are popular among collectors for their unique appearance.
