Argyroderma pearsonii


GeneralitŠ°


this genus includes only 5-10 species, originating from southern Afica, are often called "living stones", like other succulents; they are small plants, 2-3 centimeters high, without stem, consisting of two paired leaves, very fleshy, which give the plant a rounded shape, divided by a deep central fissure; A. fissum has cylindrical leaves, 4-5 cm long, very wide apart; often they produce numerous basal shoots, which develop near the mother plant, giving rise to small groups. In spring or autumn they produce small flowers, which emerge from the crack between the two leaves; they are similar to small daisies, with many linear petals, of yellow or purple color. During the summer the leaves tend to dry out, giving rise to a new pair of leaves, between winter and spring.

Exposure


these plants need to be grown in a partially shaded place; exposure for a few hours to direct sunlight gives the leaves a particular silvery shade; they do not fear the cold very much, and can also withstand temperatures close to 0 / -1 ° c, but only if completely dry; for a balanced development it is recommended to cultivate the Argyroderma at temperatures not below 10 -12 ° C, at home or in a cold greenhouse.

Watering


from October to May watering sporadically, waiting for the soil to be very dry between one watering and another, if they are kept at temperatures below 4 -5 ° C suspend watering; in the warm months water only when the skin of the leaves tends to become covered with fine wrinkles, an unequivocal index of dehydration; these plants can withstand even prolonged periods of drought, so in indecision it is advisable to avoid watering rather than supplying water once too often.

Ground


they are grown in very well drained soil, consisting of sand and gravel with a fairly fine grain size. In nature they grow almost completely underground, but in pots it is good to keep the leaves raised a few centimeters from the growing medium, to better control their humidity.

Multiplication


it occurs mainly by seed, which the plant produces easily, like all aizoaceas; the plant can also be propagated by removing the side shoots.
