This member of the Euphorbia family was given this name by Carl Linnaeus in 1753. It is found in southern North America and South America - and introduced in many other areas. It is growing in a well drained soil with some water and some to lots of sun. The caudex can grow to six centimetres in diameter, the entire plant to 60 centimetres in height. The flowers are white and numerous.
The genera name; Euphorbia dates back to the first century BC, where King Juba II of Mauritania used it in a reference to his doctor, Euphorbos, and that name was kept as a generic name by Carl von Linnaeus. The species name from the leaves resembles to the genera Hypericum.
