The South African Euphorbia horrida .v nova closely resembles the North American Hedgehog cactus (Echinocereus) with its short, candle like clumping stems. However, these are covered with a bright silver chalky exterior that almost glows in the dark. They also excrete a milky sap that can be an irritant. Use gloves when handling. They are slow growing to form a large clump of hundreds of stems to 1.5 meters (5 feet) wide. Avoid growing them in extreme weather such more than 10 days above 38C or 100F, and also protect them from freezing temperatures in winter. To maintain the bright silver stumped compact form give them as much sunlight as possible, except for in the low desert summer. Yo are bidding on one of the specimens shown. All stems are included.
