Euphorbia flowering very yellow

The false flowers of euphorbias hold great attraction for insects and other pollinators, like the two unlikely lunch partners sharing a meal in picture. The photo was taken in the Walter Sisulu National Botanical Garden. The strikingly yellow-flowering plant could not be identified.

Euphorbias are found in many parts of the world. They include the poinsettia, botanically known as Euphorbia pulcherrima, from Central America. E. ampliphylla of East Africa may be the tallest of the genus, reaching around 30 m in height. In China many Euphorbia hybrids based on E. milii are grown for their large and attractive (false) flowers. They are thought to be lucky plants that bring fortune to their owners, although often bearing the common name of crown-of-thorns.

Few genera of flowering plants consist of more species than the about 2000 of Euphorbia (iNaturalist; Wikipedia).
