Eriosyce curvispina santiagoensis

Description: Plants are usually solitary. (But nowadays the var. santiagensis is considered none other than a synonym of E. curvispina, which is one of the most variable taxons in appearance. I n fact, there are a number of varieties very different-looking, but not all the authorities recognize the different population as segregate varieties.)
Stem: Globular, up to 15 cm.
Spines: Long, stiff, greyish-brown spines, with darker tips. Young spines are almost black, while older ones turn greyish.
Flowers: Flowers are about 4 cm in diameter.

Cultivation: It is a summer-growing species. It's easy to cultivate, but somewhat rot prone if kept in a non ventilated place. It requires a very quickly draining/drying soil. Water regularly in summer, but do not over-water.
It needs a full sun exposure (or light shade). Good heat tolerance. Hardy to at least -5°C (but it can probably tolerate - 10° C for brief periods)

Propagation: Usually propagated from Seeds. (It seldom produces offsets).
