to this genus belong about twenty species of succulent plants, originating from the African continent. They have long stems, erect or even prostrate, depending on the species, of green or greyish-green color, up to 40-50 cm tall; they have evident ribs, from six to 10-12, consisting of hexagonal tubercles, without thorns or with short tender light spines. In the summer months they produce some small flowers, which bloom on short peduncles, almost absent, in the apical part of the stems; the flowers are white, yellow, orange or red, depending on the species, in the shape of a star, with fleshy petals; followed by the fruits, pods containing the small seeds. With age the stems tend to branch to the base or to creep, giving rise to disordered tufts. Some species, such as E. cereiformis, are very reminiscent of columnar cacti.
they should be grown in a bright place, but not excessively sunny, especially during the summer season; the winter minimum must not be less than 8-10 ° C.
water moderately from March to October, waiting for the soil to dry perfectly between one watering and another; during the cold months water sporadically, especially if the plant is kept at temperatures below 15-18 ° C. During the vegetative period add to the irrigating water of the fertilizer for succulent plants, every 20-30 days.
the echidnopsis are grown in a good rich and fertile soil, very well drained; you can prepare an ideal soil by mixing two parts of universal soil, with two parts of sand and two parts of lapillus or pumice stone.
it happens by seed, in spring; in the same period it is also possible to practice cuttings, the stems root very easily if they come into contact with the ground.
