to this genus belong about twenty species of succulent plants, originating in the African continent. They have elongated stems, erect or even prostrate, depending on the species, of green or greyish-green colour, tall up to 40-50 cm; they have evident ribs, from six to 10-12, formed by hexagonal tubercles, without thorns or with short, tender, pale, thorns.
During 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, star-shaped, with fleshy petals; then follow the fruits, pods containing the small seeds. With the age, the stems tend to ramify at the base or to tiller, giving origin to disordered tufts. Some species, such as E. cereiformis, are very reminiscent of columnar cacti.
should be grown in a bright place, but not too sunny, especially during the summer season; the minimum temperatures in winter should not be below 8-10°C.
water in moderation from March to October, waiting for the soil to dry up perfectly between one watering and the other; 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 water some fertilizer for succulent plants, every 20-30 days.
