succulent shrub, native to southern Africa, in nature reaches 100-120 cm high. It has cylindrical stems, poorly branched, erect, characterized by 4-5 ribs, dark green in color, the ribs are characterized by long pointed spines, the new spines are dark brown (hence the name of the plant), become gray with the passage of time. In spring, at the apex of the new spines, small yellow flowers bloom.

Very showy plant, it tends, with the time, to produce wide roundish cushions, very showy; in spring, the contrast between the dark thorns and the flowers of intense yellow colour is decidedly of strong impact. Let’s remember that the latex contained in the euphorbia plants can be poisonous if ingested and can cause skin irritations; therefore let’s handle the plants with care.

Exposure

they love very sunny locations, where they can enjoy a few hours of direct sunlight every day; they can bear short frosts, but it is advisable to grow them, during the cold months, in the house or in cold greenhouse, so that they are protected from excessively harsh temperatures. Even in the house let’s keep them in a very bright place, possibly sunny.

Watering

euphorbia water only when the soil is very well dry; from March to September watering must be regular, more or less abundant depending on the climate. During the winter we can thin the watering, but remember to moisten the ground sporadically.

Land

it needs a soft and very well drained and permeable soil, in order to avoid water stagnations; let’s prepare an ideal substratum by mixing a part of peat, a part of pumice stone and a part of washed river sand. These plants are preferably grown in pots, so that we can move them with the arrival of the cold, remember to repot them every 3-4 years.

Multiplication

occurs by cutting, quite easily, by removing one of the lateral branches; in order to facilitate the development of new roots, it is advisable to immerse the terminal part of the branch in the rooting hormone, before burying it; the young plants thus obtained are not to be watered for some days. In spring, it is possible to sow the small seeds, which are to be kept humid and in a semi-shady place.
