Euphorbia alluaudii subsp. oncoclada
Succulent likes sunny and semi-shady habitats.
Always water a few days after the substrate has dried out. In winter, limit watering.
It can tolerate -6.7 °C in the short term. However, the plant is not hardy.
There are several similar species in the countryside of south-west Madagascar. They grow here in the thorn bush and are very similar to each other in body structure.
Euphorbia alluaudii subsp. oncoclada is also known as Cat Tails Euphorbia, Bush Euphorbia, Milk Bush, or Pencil Tree. It is native to southwestern Madagascar. This subspecies is found in thorny scrub on coral limestone and is related to other species of this region with similar appearance.
The green leaves are usually up to 1.3 cm long in summer and leave brown spots on the stem when they fall. The narrow, yellow-green, cylindrical branches are up to 1.5 cm in diameter and grow initially upright, later becoming arching. A densely branched shrub or small tree, it grows up to 4 m in nature, but in our area it grows considerably less.
Small yellow-green flower structures (cyathia) appear in spring and summer. The cyathia bear even smaller flowers and are loosely clustered at the ends of the branches. The fruit is a red heart-shaped capsule with three lobes. One seed is commonly found in each chamber.
The succulent also has a cristate form and grows rather slowly. It can be lightly fertilised with e.g. cactus and succulent fertiliser. In time, the Madagascar sedge will form a majestic shrub that will impress your neighbours.
