Columnar stems are densely covered in white wool (actually white radial spines that have evolved to resemble "hairs"), that totally obscures body of plant. Some bright red spines are visible above the wool . Flowers are violet red and semi-tubular in shape. Bright light for best appearance. In cultivation, Oreocereus requires bright light to produce dense hairs, but, as a former mountain dweller, does not care for extremely high temperatures. Water thoroughly when soil is dry. Do not overwater during cold winter months. Preferable not to water on overcast days, humid days or cold winter days.

How to Care for the Plant
Water
Water well during the Summer and then allow the surface of the compost to dry before watering again. During the Autumn and Winter, keep this cactus dry, giving only enough water to prevent it from shrivelling. This plant will soon rot if kept wet at low temperatures.
Fertilizer
Feed regularly every 1-2 weeks during the Spring and Summer. Use a proprietary cactus food, or one recommended for tomatoes at about half strength.
Sunlight
Provide this plant with bright light at all times; it will grow happily in a South-facing window.
