genus that includes about twenty species of succulent plants, originating in southern Africa. They form tufts consisting of a few columnar spindles, at most 35-40 cm high, of dark green or greyish-green color. They are furrowed by deep ribs, on which there are numerous thorns, more or less sharp depending on the species; the general appearance of these succulents is very reminiscent of the cactaceae, from which they are very clearly distinguished by the flowers: of variable size, they are roundish, flat, with five petals, red or brown, covered with a light down, emanate usually a very unpleasant smell, like rotting flesh.
put to stay in a partially shady place, that enjoys some hours of sun in the morning and not in the hottest parts of the day; these plants in general can withstand temperatures close to zero, but develop best with minimum winter temperatures close to 10-15 ° C.
water sporadically, from March to October, being careful to let the soil dry for a few days between one watering and another. In winter, avoid watering, especially if the plants are kept in a cold or temperate greenhouse. In the vegetative period, mix the water with the fertilizer for regular plants, every 30-40 days, in half the dose recommended on the package.
hoodia prefer loose, very well drained, sandy soils; an ideal substrate can be prepared by mixing a good quantity of sand and medium-fine grain pumice stone with universal soil. These plants tend to thicken and grow much with the passing of the years, so it is advisable to plant them in sufficiently large containers.
it occurs by seed, in spring, or by division of the tufts, in spring or autumn.
