Mimicry : Stone Faces

Lithops, or also referred to as pebble plants, are succulents that grow extremely slowly and rarely get more than 1-inch above the soil. They usually only have a pair of leaves, which look more like stones than leaves with a fissure separating them (small gap) and epidermal windows (the small holes on top of the leaves) 

Light

4-5 hours of early sunlight, and partial shade in the afternoon

Water

water your Lithops once every 2 weeks (at most) beginning at the end of summer, where this plant is actively growing. But once the winter season hits, it's best to leave it be and not water at all
