Browningia hertlingiana
A tree-like columnar cactus famous for its turquoise-blue stems, native to the dry inter-Andean valleys of the Mantaro and Apurímac basins in southern central Peru. It grows in strong sun with mild days, cool nights and a long dry winter, and the blue colour is best under bright light.
Where it grows wild
Dry inter-Andean valley slopes with scrub and other columnar cacti, on rocky, well-drained soils. Details here come from the measured sites and general knowledge of the species.
Usually about 2,000–3,000 m in dry valleys; one climate site at 3,844 m is probably too high.
