Description
Copiapoa dealbata is a cactus that forms impressive mounds reaching up to 3.3 feet (1 m) in height and more than 6.6 feet (2 m) in width. The stems are spherical to short cylindrical and can measure up to 6.4 inches (16 cm) in diameter. They are grayish-white with a wooly apex and have only one (sometimes 1 to 3 smaller) spines per areole. The needle-like spines are black to light brown, becoming grayish-white with age, and can grow up to 2 inches (5 cm) long.
In summer, the stems produce pale yellow flowers that can reach up to 1.4 inches (3.5 cm) in length and diameter. It usually takes 6 to 10 years before the stem blooms.

Hardiness
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Despite the extreme and specific conditions in their natural habitats, Copiapoas are surprisingly easy to cultivate. This genus is very forgiving, from seed sewing to caring for mature plants. While maintaining size, Copiapoas in cultivation will flower from a young age and reliably so each following year.
These cacti want exposure to half or full sun. If they are in full sun, they must be in a position with good air circulation or risk sunburn.
Watering should be extremely poor. The soil must dry out completely between waterings. Watering should, however, be suspended during mid-summer. In this period, instead of watering, spraying the plant early in the morning, before the temperature warms up, thus simulating the conditions they would have in their natural environment will be appropriate.
The soil should be formed from a mineral substrate (granite crumbled) mixed with very little universal soil.
