In the wild, Peru to Ecuador, these columnar cacti can reach the size of smaller trees; however in cultivation they are different. The size grows to 3' and unlikely to have more than just one stem. Even though the stems are covered with white hairs, many people fail to see the possible, awful outcome. The stems are sharp, yet the white hair stops people from realising. Obviously they are not as bad for those in peoples’ houses, but can be devastating in the wild.
The Espostoa lanata, from Peru, is the most commonly kept cacti of this genus. They are easy to grow from seeds and as said above, great to see.
