Copiapoa cinerea

Scientific Name
Copiapoa cinerea

Geographic & Climate

• Geographic Coordinates: 24°00'S to 26°30'S (Coastal desert ranges of Antofagasta and Atacama regions, northern Chile)

• Climate Classification: BWh (Hot desert climate) / Hyper-arid coastal desert zone

• Habitat Characteristics: Elevation ranging from sea level to 850 meters. Precipitation is nearly zero, with moisture exclusively sourced from dense, recurring coastal fog (Camanchaca) concentrated during early mornings and late afternoons. Substrate consists of highly mineral, rocky, and gravelly slopes exposed to intense ultraviolet radiation.

Botanical Morphology

• Diagnostic Features: Globular to columnar stem growing up to 1.2 meters tall and 10-20 cm in diameter. Features a thick, chalky-white to ash-grey waxy epidermal coating produced under high UV exposure to prevent desiccation, contrasting sharply with dense, woolly greyish-white apex and sparse, rigid, jet-black central spines (1-2 spines, up to several centimeters long). Ribs number 12 to 30, broad and obtuse. Flowers are yellow, funnel-shaped, 1.5 to 2.5 cm in diameter, emerging from the crown.

• Growth Habit: Solitary to slowly offsetting columnar cactus with an extremely slow growth rate. Summer-growing cycle with strict dormancy requirements; maturity for flowering typically requires 6 to 10 years of intense light exposure.

History & Etymology

• Etymology: The specific epithet "cinerea" derives from Latin, meaning "ashen" or "like ashes," directly describing the distinct chalky, ash-grey appearance of the stem.

• Historical Context: Initially collected and described by German-born Chilean naturalist Rodulfo Amando Philippi, later formally transferred to the genus Copiapoa by Britton and Rose. It has long captivated succulent enthusiasts due to its striking adaptation to one of the most hostile coastal deserts on Earth.
