Description
Gymnocalycium ochoterenae is a small cactus with a gray-green, olive green, or brownish stem with 9 to 12 ribs. The stem is up to 1.8 inches (4.5 cm) tall and up to 3.2 inches (8 cm) in diameter. It usually has three spines per areole. They are straight to slightly curved, brownish-yellow to whitish-yellow with a darker tip, and up to 0.6 inches (1.5 cm) long. Flowers are funnel-shaped, white with a pale pink throat, up to 2.6 inches (6.5 cm) long, and up to 2.2 inches (5.5 cm) in diameter. Fruits are barrel-shaped, green to dull red, up to 1.2 inches (3 cm) long, and up to 0.8 inches (2 cm) in diameter.

Hardiness
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Some Gymnocalyciums are shade-seeking in the wild, among shrubs or grasses, while others grow completely exposed. Therefore, some will need light shading from the sun in the hottest months, but to overdo it, it will lose flowers.
The balance of the potting medium should be sufficient to allow proper drainage so that the plants do not sit in soggy soil for more than a day or two after watering.
Watering in the summer months, while the plants are growing well, can be frequent (weekly for small plants in small pots) but always allows the compost nearly to dry out before rewatering. Watering in the winter months at all is unwise and certainly not necessary. The difficult times are spring and autumn.
Those species which produce offsets can be readily propagated by cuttings. Gymnocalycium seed germinates well when fresh and will keep for a few years if stored in cold conditions.
