Copiapoa cinerea is a very variable species as
demonstrated by the number of varieties and their synonyms. The several
classifications and reclassifications provide evidence of the confusion
that rules regarding the names used in this highly variable species. It
seems that many botanists and hobbyists who have studied Copiapoa in
habitat have formed their own concepts of which names should be applied
to which plants. It is relatively easy to attribute some key features
that dominate in certain populations, but it is equally possible to look
more closely at plants in these populations, and find individuals that
'break the rules' and would easily fit another population's dominant
characteristics.

Cultivation: This
extremely slow growing cactus is kept for the beauty of its form, it
must be protected from excessive heat and sun in
summer, and seems to do best in cultivation with a bit of shade.
Requires light but regular waterings in summer, but let the soil
mix dry between waterings.
Prone to rot if
overwatered. 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.
