Cleistocactus Strausii Hybrid Cactus Great Purple Flower

Cleistocactus strausii is native to high mountain regions of Bolivia and Argentina.
Its thick, erect, grey-green columns can reach a height of 3 m (10 ft). The columns are formed from around 25 ribs and are densely covered with areoles, supporting four white spines up to 4 cm (2 in) long and 20 shorter white radials. The cactus prefers free draining soils, strong sunlight, but not high temperatures — in fact it can withstand hard frosts down to the mid twenties. In its natural habitat it receives plenty of water during the summer, but almost none over the winter.
