Copiapoa cinerea is a species of the genus Copiapoa in the family of Cactaceae. The epithet cinerea comes from the Latin word for ash, by reference to the colour of the epidermis.

It comes from the region of Antofagasta and the coastal zones of northern Chile. The area is very arid. However, there are dense fogs, due to cold streams of the Pacific ocean. These fogs are frequent, in early morning or late afternoon at an altitude between 500 and 850 m (1,640 and 2,790 ft).

The ash-grey to white coloured epidermis contrasts with typically black spines and woolly crown when adult.

Description

This cactus is globular, then columnar up to 1 m (3.3 ft) tall, 20 cm (7.9 in) in diameter, with 30 ribs. Only old plants offset from the base.

The light coloration is a protection against desiccation. In culture, the epidermis is often greenish.

Flowers are yellow, with a diameter of 2.5 cm (0.98 in), at the top of the plants.

Cultivation

C. cinerea is slow growing and hard to keep, because of the risk of rotting. Grafting is a solution. It rarely flowers in cultivation. Before all, it needs well drained soils. Sunny place, but protection against excessive sun in summer. In summer, it needs light and regular watering, but let the soil dry between two waterings. In winter, keep warm (no less than 8°C) and absolutely dry.

Synonyms

An old copiapoa cinerea
