this family comprises only one species, native to South Africa. It is a small, greyish-green succulent, but may look different depending on the substrate on which it is grown. It has a very small stem, from which depart large fleshy leaves paired, with rounded tips, the top page is usually flat, while the bottom is very rounded.
Usually this succulent does not grow much, because the leaves have a fairly short life, the tufts usually count 2-3 pairs of leaves, but often tend to widen by creating new groups of leaves. In the middle of summer, they produce large flowers, often larger than the leaves, of yellow or orange colour, formed by tufts of long thin petals, similar to those of the daisies.
lapidary plants like very bright positions, they don’t always develop well in the shade; they fear the cold, therefore in winter they are to be admitted to the house or to a temperate greenhouse, as the minimum temperature is around 10°C.
do not need great qualities of water, water moderately in spring and summer, thin watering with the approximate winter, when water is provided every 20-30 days. When a new copy of the leaves grows in the centre of the rosette, usually the older leaves begin to dry up, in this period we suggest to water even more rarely, as the plant does not need water, using the one contained in the leaves which are drying up.
From April to September provide fertiliser for succulent plants at least once a month, dissolved in the water of the watering.
it needs a fairly fertile soil, without partiular exigencies, provided it is well drained; it can be used some good mould for succulent plants, or some universal balanced mould lightened with sand and pumice stone. These plants do not need to be repotted often.
takes place by seed, utilizing the fresh seeds, and placing them in a container filled with sand and peat in equal parts; keep the seedbed in a place with constant temperature, around the 15-18°C, and quite humid till when the small plants are of sufficient size for being able to be handled, then placing them in single containers.
