The beautiful Snow on the Mountain (Euphorbia maginata) plant is a very common sight in late summer. A member of the spurge family, it is a cousin of the Poinsettia (Euphorbia pulcherrima), itself a wildflower native to Mexico.
Sometimes known as "ghostweed", the bitter tasting, milky sap can cause nausea, vomiting and diarrhea when ingested. The sap can also cause severe dermatitis if allowed to remain in contact with the skin.
