Cultivation:
It is a summer-growing species that offers no cultivation difficulties.  Water regularly in summer (but do not over-water). It is rot prone, and should be planted in a shallow pot.  Like most Echinopsis cultivated for their blossoms, it needs a soil mixture that's a little richer than for the average cactus, still with excellent drainage.   Keep rather dry in winter.

It is quite frost resistant if kept dry (hardy to  -5(-18) C
 Outside full sun or afternoon shade, inside it needs bright light, and some direct sun.

Propagation: Sow directly after last frost, offsets (if available).
