    "Euphorbia is a genus of flowering plants belonging to the family Euphorbiaceae. Consisting of 2008 species, Euphorbia is one of the largest and most diverse genera in the plant kingdom, along with Rumex and Senecio. Members of the family and genus are commonly referred to as spurges.

    The plants are annual or perennial herbs, woody shrubs or trees with a caustic, poisonous milky sap (latex). The roots are fine or thick and fleshy or tuberous. Many species are more or less succulent, thorny or unarmed. The main stem and mostly also the side arms of the succulent species are thick and fleshy, 6–36 inches tall. The deciduous leaves are opposite, alternate or in whorls. In succulent species the leaves are mostly small and short-lived. The stipules are mostly small, partly transformed into spines or glands, or missing.

    The milky sap of spurges (called "latex") evolved as a deterrent to herbivores. It is white and colorless when dry, except in E. abdelkuri, where it is yellow. The pressurized sap seeps from the slightest wound and congeals after a few minutes in air. The specific composition of diterpene or triterpene esters varies, and determines how caustic and irritating a particular species is. In contact with mucous membranes (eyes, nose, mouth), the latex can produce extremely painful inflammation. Therefore, spurges should be handled with caution and kept away from children and pets. Latex on skin should be washed off immediately and thoroughly. Congealed latex is insoluble in water, but can be removed with an emulsifier like milk or soap. A physician should be consulted if inflammation occurs, as severe eye damage including permanent blindness may result from exposure to the sap. When large succulent spurges in a greenhouse are cut, vapours can cause irritation to the eyes and throat several metres away. Precautions, including sufficient ventilation, are required."

    Feature cushion sprite at the front of a border for its symmetrical mounded form, bright spring bracts and reddish fall foliage. Place the taller euphorbia in the middle or back of a border, where they are valuable for both their colorful grafts and their handsome foliage. 'Fire Glow' euphorbia's bronze-tinted leaves go well with red, orange or yellow flowers.
  • Posted by SongofJoy (Clarksville, TN - Zone 6b) on Feb 4, 2012 3:15 PM concerning plant:
    The common name "spurge" derives from the Middle English/Old French word "espurge" which means "to purge" (due to the use of the plant's sap as a purgative).

    The botanical name Euphorbia comes from Euphorbus, the Greek physician to King Juba II of Numidia (d. 23 AD) who married the daughter of Anthony and Cleopatra. He noted that one of the cactus-like Euphorbias was a powerful laxative. In 12 BC, Juba named this plant after his physician, Euphorbus. Botanist and taxonomist Carl Linnaeus assigned the name Euphorbia to the entire genus in the physician's honor.
