6 beautiful and healthy rare succulents Lithops . Lithops, (commonly called "flowering stones" or "living stones") are true mimicry plants: their shape, size and color causes them to resemble small stones in their natural surroundings. The leaves are thick to store enough water for the plants to survive for months without rain. The plants are small and keep a low profile to minimize the effect of the intense heat and light of their climate. Lithops do well if they receive about 4 or 5 hours of direct (or only slightly filtered) sunlight during the early part of the day, and partial shade during the afternoon. Will ship bare rooted.
