The Oreocereus arboreus is a remarkable columnar cactus known for its distinctive white woolly hairs and long, sharp spines. Native to the high altitudes of the Andes, it forms tall, branching stems with prominent ribs covered in dense, silky hairs that protect it from intense sun and cold. The spines, ranging from golden yellow to reddish-brown, pierce through the wool, adding a dramatic contrast. In late spring, it produces tubular red to magenta flowers near the stem tips, attracting hummingbirds. Its majestic, tree-like appearance makes it a standout in any cactus collection.
