Oreocereus

 

Oreocereus contains a small number of columnar cacti coming from high altitude areas in the Andes mountains of South-America. They vary in shape from prostrate clusters to 10 feet tall columnar species (3 m). All the species are covered with an abundant hair like material that protects them from the sunlight, and probably also from abrupt temperature variations. The name Oreocereus comes from the Greek for 'mountain Cereus'.

Mature cacti produce showy light colored flowers in summer. The Oreocereus are generally propagated from seeds.
