Euphorbia triangularis cristata
Place ideally in a sunny position or in partial shade.
Always water a few days after the substrate has dried out. Generally water less and hardly at all over winter.
It can tolerate down to -3.9 °C in the short term. However, the plant is not hardy.
It is a succulent, but its crested growth and spines make it very similar to a cactus.
Euphorbia triangularis cristata resembles a cactus rather than a succulent, which it is. The native plant is native to South Africa and the cristate form grows much slower. It can sometimes be traced under the name Euphorbia jubata cristata.
The green, wrinkled, fan-shaped stem is adorned with pairs of robust spines. These change colour from whitish to brown with age. The very sturdy stem has clearly defined ribs and grows to a height of about 30 cm.
The crested form is unlikely to flower.
Care should be taken when handling as it will produce a slightly toxic latex when injured. The succulent can be lightly fertilised with, for example, cactus and succulent fertiliser. The slow-growing Euphorbia triangularis cristata is highly prized among collectors for its original form. The crested growth makes each individual specimen unique and will add a touch of something unusual to the place where you grow it.
