One of the most popular and collected indoor flowers are lithops, which are also called "living stones" or "stone flowers". The name of these succulents comes from the ancient Greek lithos (λίθος - stone) and ops (ὄψ - face) because of their natural color, which merges them with inanimate nature in their natural waterless areas. And on the planet they are found only in Africa - Namibia, South Africa, small border areas of Botswana and most likely Angola. About a thousand populations of lithops have been found so far. Each of them occupies a small area in dry grassy, ​​green or completely rocky areas. They can exist where another plant would not survive, and thanks to the peculiar form of mimicry, they remain unnoticed and protected. Different lithops are located in different places, usually adapted to a certain type of rock formations, but in the natural environment they exist only in these groups and nowhere else. There the annual value of precipitation varies from 700 mm to 0 mm, and the temperatures from very low, through moderate to extremely high. Most lithops rely on summer or winter rain, and some only on dew for moisture.

The first description of these succulents was made in 1811. from the botanist and explorer of South Africa William John Burchell, who accidentally discovered them by lifting from the ground a "stone of interesting shape". Over the years, different species continue to be found in different places, but for a very long time they cannot be placed under a common denominator. New representatives of lithops are still found today - sometimes in isolated places and sometimes in populated areas. However, their exceptional camouflage often leaves them unnoticed.
Selling them in the form of seeds or plants in stores or on the Internet turns them into unique and collected indoor flowers. They are relatively easy to grow - they need dry and sandy soil, lots of sun and imperceptibly little water.

The soil environment in which lithops are grown should not retain any moisture, because its absorption will swell them and they will break their shell. Exposing them to strong sunlight will make them bright, with a hard and rot-resistant shell, although overwatering remains a fatal threat. Each individual plant consists of a pair of almost connected leaves, most of which remain underground. Their upper side is translucent and allows light to enter the leaves and ensure photosynthesis. Therefore, the lack of enough light can be as detrimental as the presence of water. On the other hand, although in natural conditions lithops are resistant to very high temperatures, when grown in pots should not be overheated, because natural soil cooling is almost impossible. Unlike many other species, "Stone Flowers" rest during the hot months, most of which grow during the winter. The gap between the leaves contains the meristem (forming tissue) and from there the flowers and new leaves appear.
