This large genus of around 2,000 species of annuals, perennials, shrubs, and trees, both evergreen and deciduous, is distributed throughout the world. It covers a diverse range of forms and natural habitats, from the spiny and succulent cactuslike species of hot dry areas to leafy perennials from cooler temperate climate. The tru flowers, borne singly or in clussters, are very small and insignificant, but are often accompanied by long-lasting, colorful, petallike bracts. All species contain a irritation and, sometimes, temporary blindness on contract with the eyes. The purgative qualities of the sap are acknowledged in the common name spurge, from the Latin word expurgare, meaning to purge.
CULTIVATION
The diversity of form makes it difficult to generalize cultivation requirements. Consider the plant's natural habitat, and provide similar growing conditions. Because of the toxicity of the sap, care should always be taken when handling these plants. Some species are propagated from seed or by division, while others grow from stem-tip cuttings.
Top Tip
One of the most popular Euphorbia species is the poinsettia from Mexico (E.pulcherrima), which need fertile soil and plenty of sunshine to grow successfully.
