Cleistocactus aurantiacus

Cleistocactus aurantiacus is a cactus species that grows as a shrub up to 2 meters tall with slender, green stems that branch from the base. It can reach several meters in height and features 10 to 15 rounded ribs along its stems, with areoles located on each rib. From these areoles, slender spines emerge; radial spines are more numerous and shorter than the central spines. The plant produces numerous individual flowers that emerge from the areoles. These tubular flowers have barely open tips and are bright orange in color. The small, densely scaly fruits contain many seeds.

This species is native to Bolivia and typically grows in desert or dry scrub environments.
