Peanut Cactus
BeginnerEchinopsis chamaecereus
A small cactus of finger-like stems that cluster and trail, opening a succession of vivid orange-red flowers. Hardy and free-flowering, it is an easy favorite.
About
The peanut cactus (Echinopsis chamaecereus, formerly Chamaecereus silvestrii) is a small cactus from the mountains of northwestern Argentina (unrelated to the fragrant sandalwood that shares its Japanese name, byakudan). It is distinctive for its many finger-like stems, about 1-2 cm thick and 10-15 cm long, that cluster and trail over the pot rim, clothed in soft white spines. Its chief appeal is prolific flowering: from spring into early summer it covers itself in vivid orange-red trumpet flowers. Very hardy and easy, and propagated simply by cutting and rooting a stem, it has long been a popular beginner cactus. It likes a sunny spot — too little light reduces flowering — and is watered when dry during the growing season and kept dry and dormant in winter. Relatively cold-tolerant, it also suits a hanging pot where its stems can trail.
