The roots of the name Pleiospilos come from the Greek Pleios = many, Pilos = spots, plants with many spots. Of this plant, native to Sub Africa, 38 species are known and belongs to the plants nicknamed stone-plants (such as Lithops). It is a succulent plant, composed of a very short stem, which in some species does not come out of the ground. The stem usually carries groups of 2/4 fleshy leaves. In the apical part of the plant there are very showy daisy-shaped inflorescences.
The cultivation is done in small pots (8-10 cm) using a fairly sandy mixture. Very important for these plants is the drainage, which is done by placing gravel at the bottom of the pot.
It must never fall below 6-7 °C. In the autumn and winter months it is advisable to stop watering, while in the warmer months it is possible to irrigate monthly. During the spring period the Pleiospilos plants have a natural change of leaves, those of the previous year dry up leaving room for the new ones. In very hot periods it is advisable to add mild amounts of fertilizer to the water.
- Plants in nature tend to adapt to the most disparate conditions; to do this many plants have taken very particular forms, which with difficulty we can bring back to the concept of piousness.
It occurs by sowing or by division of the caespitose plants.
Sowing is carried out in the period from March to April, taking care to maintain the temperature at 20°C.
The multiplication by division takes place in spring, dividing the mother plants from the daughters, taking care to take the stem with a little bit of roots. Rooting is not difficult and after a short time you can start to water the young plants.
The best known varieties are:
Pleiospilos bolusii: Varietà
P . bolusii: plant that reaches the 10 cm of height, formed by 1 or 2 pairs of very stubby green-grey leaves, angular, wide, with black spots. The leaves tend to darken in the presence of strong light intensity. Flowering is composed of yellow daisies and takes place in summer/autumn. The blooms are disproportionate to the plant, in some specimens the flowers completely cover the leaves.
P. simulans: plant very sensitive to low temperatures, minimum 6 °C, composed of 1 or 2 pairs of gray-ambered leaves, with an enlarged shape very similar to the previous variety. The plants can reach a width of 30 cm but only reach a height of 10 cm. Flowering takes place in the summer/autumn months, the flowers are yellow and have a fragrance similar to coconut.
P. nelli: Very similar to the variety P. bolussi, but much smaller, the leaves are much stockier and have a slightly grayer coloring, with the presence of many black spots. Flowering takes place at the same time as the previous species. The flower, with orange petals, is white on the inside.
