Oreocereus trollii
Oreocereus trollii, commonly known as the Old Man of the Andes cactus, is a species of cacti native to Argentina and Bolivia.[1] Named after Wilhelm Troll,[2] its common name comes from the abundant white hairs surrounding the plant which serve to protect it from scorching sunlight and frosts in its mountain habitat.[3] Slow growing, O. trollii produces red flowers, typically after reaching several feet in height.[1] Though listed as Least Concern by the IUCN, the plant is collected extensively, and in some areas is threatened.[4]
