Habitat

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. It is widespread in its habitat and quite variable in size and spines, and for this reason it has received several names.[2]
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 central spines are mainly hidden by the woolly radial spines. It branches only after several years.[2]
It flowers at night from a lateral cephalium after several years.[2]
Woolly hairs have been used for pillow filling in Peru.[2]

Cultivation
Source :[2]
Espostoa lanata is easy to grow. It needs fertile and well-drained soil. In summer, water the plants well but allow them to dry before watering again. Use monthly a fertilizer for cacti.
In winter, keep it dry and the temperature may be as low as −12 °C, but it is better to keep it without frost.
The exposure must be sunny in summer and at least luminous in winter.
In favorable conditions (sun, water, large place), it can grow 20 cm every year.
