Copiapoa krainziana var. brunispina Photo by: Valentino Vallicelli
is a striking slow growing species that forms large clumps with age.
It is easily distinguished by long whiskery spines that vary in colour (the 'brunispina' is the brownish coloured form). The globular body freely offsets into a mound.
Origin and Habitat: Endemic to a very small area in Chile, II Region Atacama desert, Antofagasta, north of Taltal, coastal mountains, 500 - 2000 m. Typical area is San Ramon Valley.
Habitat: This species strives fully exposed to the sun in extremely dry areas with very rare rainfall, on hills and canyons on plains and on slopes facing north. They often grows mingled with clumps of Copiapoa cinereaSN|1380]]SN|1380]] forma haseltoniana and columnar Eulychnia. The dry season lasts 8 - 12 months and in some years it is possible to have no rainfall at all. Rainfall less than 100 mm/year. The plants obtain water mainly from condensation of coastal fog (camanchaca). By the middle of the morning however, the fog cover dissipate and sun breaking through the gaps warming the ground.

Stems: Globose to cylindrical usually grey to green in hue, up to 12 cm wide with a woolly crown.
Ribs: 13 to 24 ribs, straight.
Areoles: Large, roundish, with grey wool.
Spines: Variable, densely distributed, needle-like, long, very thin, straight or curved, flexible usually white or greysh (or sometime brownish in the so called forma 'brunispina')
Central spines: 14 to 20 up to 2,5 cm long (or more).
Radial spines: 10 to 12 greyish approx 2 cm long.
Flowers: Clear yellow, 3.5 cm long.
Fruits: White or rose, up to 1 cm long.
Remarks: Pretty, white-spined forms need to be large before flowering; darker-spined plants grow faster.

Notes: Some authors consider that Ritter's Copiapoa krainzianaSN|1386]]SN|1386]] v. brunispina is part of a variable hybrid swarm between Copiapoa cinereaSN|1380]]SN|1380]] and Copiapoa krainzianaSN|1386]]SN|1386]].

Read More... Cultivation and Propagation: This slow growing cactus is kept for the beauty of its form and spines. It must be protected from excessive heat and sun in summer, and seems to do best in cultivation with a bit of shade. It requires light but regular waterings in summer, but let the soil mix dry between waterings, Prone to rot if over-watered. Needs good drainage. Keep warm and dry in winter (10°C) to avoid rot. Not highly tolerant of a great deal of frost. (Frost tolerance 0°C)Propagation: Seeds (or offsets if available), Grafting is often used to speed growth rate and to create a back-up to plants in collection.
