3307 Old Man of the Andes ( Oreocereus )
This is a large cacti that can be used as a centerpiece or as a patio plant. It is a stout, upright cactus that covers itself with attractive, long, white woolly hairs. This also makes a great rock garden plant. Will normally stay small in containers, they can reach up to 10 feet tall outside after many years.
Jim's Note: Oreocereus need a minimum temperature of 45° F. Grow them in rich, porous, sandy soil and let their soil dry out between waterings. Repot in the spring, when their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. However, this doesn't necessarily mean they'll need larger pots. Fill about a quarter of the pot with broken crocks, gravel, etc. to promote good drainage. Firm the potting soil. After repotting, do not water for a week or more.
