Description: Echinopsis zecheriSN|32674]]SN|9509]] (a.k.a. Lobivia zecheriSN|32675]]SN|9510]]) is a cold hardy species in the Cactus family (Cactaceae). This is one the several questionable varieties of the morphologically variable Echinopsis backebergiiSN|9502]]SN|9502]] (Lobivia backebergii), a taxon growing widespread in southern Bolivia and northern Peru. Echinopsis zecheriSN|9509]]SN|9509]] from Ayocucho is an attractive form with hard sharp spines and rather coarser flowers with rich liliac or purple petals and a white throat. However the distinguishing characteristics of Echinopsis zecheriSN|9509]]SN|9509]], appear to fall within the natural variation of Echinopsis backebergiiSN|9502]]SN|9502]] and it should be synonymized with the latter.
Note: W. Rausch, Lobivia 1985, consider this taxon an extreme form of Lobivia hertrichianaSN|9510]]SN|32675]] (Echinopsis hertrichianaSN|9509]]SN|32674]]) distinguished by the harder long spines.
Stems: Up to about 6 cm in diameter with straight ribs. Usually solitary but in age it may offsets forming small clump up to 20 cm in diameter.
Flowers: About 3-4 cm long and wide (occasionally larger), bright purple to liliac or violet with a white throat. Pistil and stamens pink to red violet. Flower colour, as elsewhere in the genus is quite variable.
Fruit: About 1 cm wide, drying at maturity with relatively large seeds.

Cultivation and Propagation: Echinopsis zecheriSN|9509]]SN|9509]] grows rather slowly and it is sensitive to overwatering (rot prone) and needs a very good drainage to avoid rotting, but requires more moisture than true desert cacti to grow and produce flower. It is a very easy flowerer, if you keep it reasonably cool and absolutely dry during winter and lots of fresh air and sunshine tends to produce better plants and more flowers.
Soil: Use a loose well drained cactus mix.
Repotting: It require a deep pot suited to accommodate the swollen root, repotting with fresh potting-mix should be done every other year or when the plant has outgrown its pot. However, repotting doesn't necessarily mean they'll need larger containers.
Sun Exposure: Light shade when young, full sun later. Outside it likes strong sunshine, but is tolerant and do well with light shade during the hot Summer months. Tends to bronze in strong light, which encourages spine production.
Hardiness: It is cold resistant to -10° ( or even less depending on clones) for short periods of time. It will show its flowers only if we provide an adequate winter rest period.
Watering: Water regularly through the growing season. This can be done weekly or more frequently during the summertime, if the weather is sunny enough, but allow to dry fully before watering again. Kept this way, plants will show a healthy growth. Keep rather dry as soon as the temperature starts dropping in October and keep it dry in winter. The plant survives outside without protection in winter but is then somewhat prone to rot, too.
Fertilization: Give an occasional high potassium liquid feed during the active growing period.
Garden uses: It is a fine plant for a rock garden or container, contrasts well with agaves, yuccas, and low-growing flowering plants.
Pest and diseases: They are generally fairly easy to grow, especially if kept pest-free. They are susceptible to, scale insects and spider mite. Watch carefully for infestations of stem and root mealy bugs, and damage from these may well initiate fungal attack.
Propagation: Seeds, also can be grown from cutting as it branches from the base. Take cuttings spring or summer, let them dry till the ends callous well. Then replant them in fresh cactus soil that is ever so slightly moist, and keep it that way till they root. Surface sowing is the best; seeds germinate in 14-28 days at 20° C, remembering that seedlings dislike strong light and dry conditions.
