Scientific Classification

Family: Cactaceae
Subfamily: Cactoideae
Tribe: Notocacteae
Genus: Copiapoa


Copiapoa esmeraldana is a low-growing cactus with green, soft, succulent stem, up to 3 inches (7.5 cm) tall, with the tip covered with white wool, particularly at flowering time. The stem has 13 to 16 ribs, deeply toothed, tuberculate, and up to 0.4 inches (1 cm) tall. Tubercles are rounded and chin-shaped. Areoles are apical, slightly dislocated in the lower part of the tubercle, up to 0.6 inches (1.5 cm) apart, covered with short, whitish wool when young, later hairless. The spines are straight, brownish to ash-grey and up to 0.8 inches (2 cm) long. Young plants only have thin radial spines, while the central spines appear as the plants mature. The flowers are yellow, bell-shaped, and up to 1.4 inches (3.5 cm) long.


USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).

How to Grow and Care

Despite the extreme and specific conditions in habitat, Copiapoas as a whole are surprisingly easy in cultivation. From seed sewing to the care of mature plants, this genus is very forgiving. While staying manageable in size, Copiapoa 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 they risk sunburn.

Watering should be extremely poor. The soil must dry out completely between waterings. They should, however, be suspended during mid-summer. In this period, instead of watering, it will be appropriate to spray the plant early in the morning, before the temperature warms up, thus simulating the conditions that they would have in their natural environment.

The soil should be formed from a mineral substrate (for example, granite crumbled) mixed with very little universal soil.
