this family includes only one species, native to southern Africa. It is a succulent of small dimensions and greyish-green in color, which, however, can take on a different appearance depending on the substrate on which it is grown. It has a very small stem, from which branch large, paired fleshy leaves, with rounded tips; the upper page is usually flat, while the lower one is very rounded. Usually this succulent does not grow much, since the leaves have a fairly short life, the tufts on average count 2-3 pairs of leaves, but often they tend to widen creating new groups of leaves. In high summer they produce large flowers, often larger than those of the leaves, of yellow or orange color, consisting of tufts of long thin petals, similar to those of daisies.
the lapidaries like very bright positions, they do not always develop well in the shade; they fear the cold, so in winter they should be kept indoors or in a temperate greenhouse, as the minimum temperature is around 10 ° C.

When a new copy of leaves grows in the center of the rosette, usually the older leaves begin to dry, in this period it is advisable to water even more rarely, since the plant does not need water, using that contained in the leaves that are drying. From April to September, provide fertilizer for succulent plants at least once a month, dissolved in the water used for watering.
