Euphorbia is a genus of flowering plants that belongs to the family Euphorbiaceae. They are commonly known as "spurges" because of the sap that they produce, which can be irritating to the skin and eyes. Euphorbia plants are native to Africa, Asia, and the Americas, and are now grown in many other parts of the world as ornamental plants and for their medicinal properties.

Euphorbia plants have a wide range of appearances, from small succulent plants to tall, tree-like plants. The flowers of Euphorbia plants are typically small and inconspicuous, and are surrounded by colorful bracts that resemble petals. The foliage of Euphorbia plants is often green, but can be quite colorful and unique, depending on the species.
