The genus Vanheerdea occurs in Bushmanland in the Northern Cape Province of South Africa. Their habitat straddles winter and summer rainfall areas. The genus is characterized by succulent yellow-green eaves with rows of small teeth on the leaf margins and keels. Each branch can produce up to three yellow-orange flowers. All species are sheathed in the summer with new leaves emerging in the fall. They need adequate water in the spring when they are active and bloom. They need lots of light to look their best.
