Called "Lebombo Euphorbia", because it was found in the Lebombo Mountains, in South Africa. Its name derives from the Latin term "confinis", which means "on the border", in fact, in nature E. confinalis grows on the border between South Africa and its neighboring countries. It is a succulent plant with a single stem, which branches at the apex only after reaching a considerable height (it can reach even 10 meters!). The light green or bluish-green trunk is covered with a few thin thorns, arranged in pairs. In late autumn it blooms with small yellow flowers.
