Echinopsis ancistrophora ssp. cardenasiana is a rare Bolivian cactus belonging to the Echinopsis genus within the family Cactaceae. Native to the Andean highlands of Bolivia, this collector cactus grows at elevation in rocky, well-draining terrain with intense sun and dramatic temperature swings.

Echinopsis ancistrophora ssp. cardenasiana forms a compact, upright globose to short-cylindrical body with clearly defined ribs lined with clusters of stout, radial spines.

It is the kind of plant that looks like it belongs in a serious cactus collection.
Echinopsis ancistrophora ssp. cardenasiana produces large, showy flowers that are spectacular relative to the plant's compact size, typical of the wider Echinopsis easter lily cactus group.

NOT water on the leaves. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour

The hotter it is outside, the faster your soil will dry out, so you’ll need to water more often if you live in a hot
area. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended
periods; protect from frost to prevent scarring.
