Oreocereus celsianus is covered in fine, dense hairs and orange-yellow spikes that look cool and help provide the plant with heat and frost protection, making it ideal for container gardens or sun-drenched garden locations. In the wild, your old man of the Andes can grow into clumps that are up to 24 inches wide and 10 feet tall. The thick covering of silky white hairs makes it challenging to describe the shape of the ribbed stem.
