Description: Echinopsis schieliana var. longispina is a morphological form of Echinopsis schieliana distinguished from the latter by longer white or brownish spines. The differences with other Echinopsis schieliana are in reality very minimal and the two plants are not readily distinguishable, if not for the spination. Best known as Lobivia schieliana var. longispina|SN|15872]] it is a cute prolific clumping cactus with dark reddish-green stems concealed by the spines and flowers are mostly a brilliant light-red and slender.
Habit: Plants generally forming clusters from basal branching.
Stems: Globose to cylindrical, often slender, to 4,5 cm long or more and 4-6 cm in diameter, dark reddish-green or blackish.
Ribs: 13-21 straight or somewhat spiralling 3-5 mm hight.
Areoles: 3-6 mm apart.
Spines: Creamy-white, yellowish or brownish, in age fading to grey.
Central spine: 1-4, often absent at first, similar to the radials but often darker, light brown to brown bent downward, up to 20 mm long.
Radial spines: 8-12(-14), pectinate to radiating, interlacing, light brown 2-15 mm long.
Flowers: orange-red to violet (or yellow) 3,5-4 cm in diameter floral bright; pericarpel 3-6 mm long and 3-6 mm in diameter, floral tubes slender 16-18 mm long, filaments violed red. Inner perianth segments violet-red with yellowish-orange or brownish-orange mid-stripe.
Fruit: Subglobose about 1 cm in diameter, dull-green to blackish, pulp white and juicy.
Seeds: 1,5 x 1 mm broad.

Cultivation and Propagation: This is a a much decorative frost hardy cactus easily found in cultivation. It is a summer grower species that offers no cultivation difficulties.
Soil: Use a very a particularly draining substratum, as it is very sensitive to rottenness when in presence of humidity and low temperatures and let the soil dry out between waterings, since it's natural habitat is in volcanic soil, it has adapted to more acidic conditions.
Repotting: Repot in the spring, when their roots become cramped. Generally, they should be repotted every other year in order to provide fresh soil. After repotting, do not water for a week or more. Needs a large pot to accommodate a large root system.
Water: In summer, during the vegetative period, it must be regularly watered, but allowing the substratum to completely dry up before irrigating again (but do not overwater ); in winter, it’s to be kept dry. Preferable not to water on overcast days, humid days or cold winter days.
Hardiness: It is a quite frost resistant cactus, hardy to -5° C (- 10° C if very dry). However in cultivation it is better not to expose it to temperatures lower than -0° C, even if in an aerated and protected location, in order to avoid the formation of anti-aesthetic spots on the epidermis. In presence of high atmospheric humidity avoid any frost as it is particularly sensitive to root rot.
Exposure: Outside full sun or afternoon shade, inside needs bright light, and some direct sun, but, as a former mountain dweller, does not care for extremely high temperatures in summer.
Use: It is suitable for small “desert” gardens, in association with other xerophytes. Where the open air cultivation is not possible due to the climate, it is to be cultivated in pot in order to shelter it in winter.
Propagation: By seeds and by cuttings, provided left drying up well, in summer.
