Eriosyce paucicostata "viridis"
 

Description: Solitary cactus with abundant white wool on top.
Stem: Subglobose to elongate, up to 15 cm in diameter. The “viridis” form has a slate blue or green body (whereas the standard form generally has a grey-purple tinged stem).
Root: Conical taproot.
Ribs:
Adult specimens have around 8-13 notched ribs, forming tubercles with sunken areoles.
Spines: Juvenile specimens have 1 central spine and 8 radials, but the numbers increase as they get older, and areoles can have over 20 spines on mature specimens.
Central spines:
Dark brown to black, soon becoming chalky-white or greyish, up to 20 mm long.
Radial spines: 6-12, up to 1 cm long.
Flowers: From young areoles,
campanulate or funnel-shaped, very pale pink, cream-white or pale yellowish with a vague green nuance. About 3 cm in diameter.  Floral tube with abundant white wool and bristles. There might be over 50 flowers on a mature specimen (only mature specimens bloom).
Fruit: Reddish, elongate, opening by a basal pore.

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 fast-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.

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