Origin and Habitat: South of the Copiapoa genus range (from the hills around the coastal towns of Coquimbo and La Serena in the province of Coquimbo) Chile.
Habitat: It grows on sandy or gravelly soils in succulent vegetation and desert scrub such as Puya chilensis, Oxalis gigantea, Heliotropium stenophyllum, Eulychnia breviflora, Adesmia argentea, Colliguaja odorifera, Flourensia thurifera and Bulnesia chilensis. The main threats in the short term are the expansion of urban areas, construction of reservoirs and farm work. While the main threat in the long term is the desertification process.Common Names include:

UKRAINIAN (Українська): Коп'япоа кокімбійськаDescription: Copiapoa coquimbana is a strongly spined cactus that branches vigorously from the base, forming large clumps or cushions up 1 m wide and 60 cm high and composed of several hundred heads. It's a highly variable taxon with several more or less similar forms that could be described as geographical varieties or, in some cases, critical species.
Stem: Elongated-globose, relatively soft, 7-15 cm in diameter, pale to bright green or bluish green, and crowned by a dense mass of long white wool, particularly at flowering time.
Ribs: There are 10 to 20 strongly tuberculate especially in young specimens
Tubercles: With a rounded, raised edge and a wide base.
Areoles: Apical, convex, covered with short wool when young, later glabrous, about 5-10 mm in diameter and 0,5-2 cm apart.
Radial spines: 5 to 10, stout, 1-5 cm long, fairly slender or slightly curved, horizontal, pointing outwards, narrowed angle to the central spine, honey-amber, brown or black, becoming grey with age.
Central spines: Absent or one or two thicker 3-6 cm long.
Roots: It has a shallow, diffuse root system or (less frequently) a short taproot.
Flowers: At the apex, diurnal closing at night, fragrant, protracting the period of opening many days, campanulate, 2,5-5 cm long, and they grow from the centre of the white wool at the apex. The outer segments of the perianth are linear red-brown or greenish. The inner segments are wide, blunt and yellow with a subtle red mid-stripe.
Fruit: About 15 mm in diameter reddish-brown, flowers remnants separate early from the fruit.
Seeds: 2 x 1,5 mm not shiny, surface with low and rounded bumps.Copiapoa coquimbana (llifle.com)
