Its common names are Peruvian old man cactus, cotton ball cactus, snowball cactus, snowball old man.

Habitat
Its original habitat is from southern Ecuador to the northern Peru on the west slopes of the Andes mountains.

Description
Espostoa lanata is a columnar cactus. It looks like Cephalocereus senilis (the Old Man of Mexico) : it is a densely hairy species, covered by a warm woolly coat and well adapted to high altitudes. The main difference is the presence of sharp spines on Espostoa. It is widespread in its habitat and quite variable in size and spines, and for this reason it has received several names. The plant is a column up to 7 meters tall in the wild, but only 3 meters when cultivated. The diameter is from 5 to 20 cm. There are 18 to 25 ribs. The ribs and the sharp are mainly hidden by tissue woolly. It branches only after several years.

It flowers at night from a lateral cephalium after several years.

Woolly hairs have been used for pillow filling in Peru.
