Cleistocactus strausii
The cactus prefers free draining soils, strong sunlight, but not high temperatures — in fact it can withstand hard frosts down to -10 °C. In its natural habitat it receives plenty of water during the summer, but almost none over the winter. In cultivation, watering too much in winter often leads to root rot.

Cactus is also an excellent fodder crop for animals and are very useful to grow under arid and dryland regions. In some parts of India they are being promoted as fodder crops.
