They are curious succulent plants with a branched columnar habit that become bushy with age and reach 4 meters (13.12 feet) in height. They have 3-4 very marked ribs with small spines on the edge. In the upper part of the plant there are some leaves, 5 cm (1.96") long, shaped like a spatula. They do not produce flowers. African Milk Tree is used in succulent gardens, as isolated specimens, in pots for terraces and patios, and as a houseplant and greenhouse. Euphorbia trigona prefers light shade exposure avoiding the sun's rays in the hottest hours of the day. It does not resist temperatures below 10 ºC (50 ºF); if it's cold or drought, it loses its leaves. The soil can be a mixture, in equal parts, of coarse siliceous sand and leaf mulch. Water moderately, waiting for the substrate to dry. Fertilize with a little compost in late winter or early spring. Cathedral cactus does not need pruning. Euphorbia trigona can be attacked by whiteflies in case of drought or by fungi if there is excess watering. Abyssinian euphorbia propagates by seeds sown in spring or by cuttings in summer. You have to be very careful with the irritating latex of these plants and protect yourself well with gloves. |
