Succulent with thorny stems and orange four-petaled flowers

Question

I just bought this plant but I don't know its name nor how to care for it.

Answer 1

Probably a variety of Euphorbia milii or crown of thorns plant. Care is easy, just give it a little water now and again and avoid getting it wet. It is native to Madagascar, so will prefer warm conditions. The flower colour is quite variable.

Answer 2

Yes this is clearly the succulent Euphorbia Milii.

From what I know this is a strong plant. The most important thing for it to thrive is to have long hours of direct sun. Behind a window would be OK, and maybe even better outside during summer.
