genus that includes 15-20 small succulent plants originating from southern Africa. They consist of rosettes of fleshy leaves, long and flat, joined two by two, sometimes arranged in a spiral, silky to the touch; the color is dark green, usually with lines, dots or streaks of a lighter color. In spring at the base of the leaves grows a stem that carries numerous bell-shaped flowers, red, pink or white, which will be replaced by seeds. G. verrucosa is a species with paired leaves, dark green, covered with white dots arranged in transverse rows; G. carinata has paired rosettes of leaves, which take various forms with the passing of the years, forming dense groups with pink flowers.
these plants do not like direct sunlight, which can cause sunburn on the leaves; they should therefore be kept in a shady place, especially during the hottest periods of the year. In winter, shelter them at home, in a bright place, they can be grown as apartment plants, since they don't fear the dry winter heat caused by domestic heating.
they do not need abundant water: from March to October water every 8-10 days, letting the soil dry well between one watering and another. In winter thin out the waterings, supplying water every 10-15 days, or even less. During the vegetative period, add fertilizer for succulent plants to the irrigating water at least every 10-15 days.
use a mixture of sand, lapillus and balanced universal soil; always keep the gasteries in a very well drained substratum, which imitates in the best possible way the soil in which they grow in nature which is usually rocky.
the gasterias tend to create new specimens connected to the mother plant through the roots, these seedlings can be detached and repotted in individual containers; in spring you can sow the seeds, or you can practice leaf cuttings, which root very easily.
