Euphorbia cooperi, also called Transvaal candelabra tree or bushveld candelabra euphorbia, is a plant species found in South Africa. This succulent tree grown up to 7 m tall and has conspicuous candelabra-like branches.
Euphorbia cooperi is a spiny, succulent tree 4-7 m tall, with conspicuous candelabra-like branches. The branches do not split again, unlike the common tree Euphorbia. Old dead branches hang underneath the compact crown for a while. Over time all lower branches shed in a continual process leaving the top branches to accentuate the candelabra form. The solitary trunk is naked, straight, grey to dark grey or brown with a gnarled appearance up to 5 m high. Round holes on the trunk indicate where old branches have fallen off. Branches are bright green or yellow-green even thought times of drought, conspicuously 4 to 6 winged with characteristic narrowing and widening and rounded tops. The spines form a spiky margin along each ridge on the branches. Spines are found in pairs and are usually 5 to 7(-15) mm long.
