Tephrocactus fiambalensis

Tephrocactus fiambalensis is a name for a small segmented cactus from around Fiambalá in Catamarca, Argentina. It is often treated as a form of, or close relative of, T. alexanderi rather than as a distinct species. Grow it like other high-desert Tephrocactus: full sun, a very mineral mix, summer water and a cold, bone-dry winter.

Where it grows wild

No wild records are available. Tephrocactus of this group grow on stony slopes and gravel plains in the arid Monte and pre-Andean valleys of northwestern Argentina, fully exposed to sun.

Not measured; the Fiambalá area of Catamarca lies roughly 1,500-2,500 m, so expect high-desert conditions.
