They have up to 25 ribs with oval areolas that have 20 yellowish spines 8 cm (3.14") long. The spectacular white, red or pink flowers can measure 20 cm (7.87") in diameter. The fruit is green and is 5 cm (1.96") long.

Due to its resistance to cold, Poco is an ideal plant to use in rockery, as isolated specimens, in small groups or in cactus and succulent gardens. It can be grown in pots when it's young.

Echinopsis tarijensis needs direct sun exposure and a dry climate. It resists occasional frosts.

Poco prefers a very well drained clay soil with coarse sand. Transplantation or planting is done in early spring.

Always water moderately, waiting for the substrate to dry; every 15 days in spring, every 7 days in summer, every 20 days in autumn and do not water in winter.

Echinopsis tarijensis appreciates a fertilization in spring with mineral fertilizer for cacti.

Pruning is not necessary.

Poco does not present problems of pests and diseases if there is not an excess of humidity and the ventilation is correct.

Echinopsis tarijensis propagates by stem cuttings or by seeds sown in spring in a sandy seedbed.
