Espostoa lanata is a species of cactus from Peru and is a columnar, densely hairy cactus, covered by a warm, woolly coat and well adapted to high altitudes.  Its common name is Peruvian Old Man cactus.  It can grow to 9 feet in cultivation.  It is different from the Mexican Old Man cactus, Cephalocereus senilis, in that it has prominent spines.   Some scientists say the wooly coat not only protects the plant against cold, it also protects the cactus from high ultraviolet light.
