Viguier’s Spurge (Euphorbia viguieri) is a succulent plant from Western Madagascar. It is named for René Viguier, early 20th century French botanist. It is not a cactus, although it looks like one. The stems of this plant are narrow at the base with emerald green leaves which are basally red. White veins are prominent on the underside of the leaves. The brilliant red “flowers” (botanically called cyathia) are erect. Euphorbia viguieri seeds will usually germinate in 10-15 days, even under good conditions germination may be erratic. Parts of this species are considered toxic.
