One of the larger and more common Oreocereus species (also the type). This South American genus comes from higher elevations in the Andes. Like a few of the others, this species is covered by long, thick, white hair and armed with stout spines. This white hair may help it harvest humidity from the air when fog is present. Purplish pink flowers give rise to greenish globose fruit which detaches and releases black seeds from the base. May be self fertile.

Usually branches at the base. Stems grow to a few inches in diameter and a few feet in height over time.

Develops brighter, thicker, and fuller hair in full sun. The hair acts as a sunscreen, making the plant very tolerant of extreme exposure in mild climates.
