Gymnocalycium Horstii (Spider Cactus) is a rare cactus that has a unique squat appearance and spines that are curved back towards the body. It grows up to 10 inches in diameter.
Its flowers are white, pale pink, pink, or pale purplish, up to 4 inches long.
All of the plants may be shipped bare root.
Full sun to light shade. Some Gymnocalyciums are shade-seeking in the wild, among shrubs or grasses. Therefore, they will need a light shading from the sun in the hottest months, but if you don’t give it enough light, this will result in loss of flowers.
It’s important to provide porous soil with adequate drainage. They will do well in sandy or even rocky soil.
Watering in the summer months, while the plants are growing well can be frequent (weekly for small plants in small pots), but always allowing 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.
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C)

Provide porous soil with adequate drainage, pots with drainage hole are recommended. Bright, filtered
light and ample airflow. Water thoroughly when soil is dry to the touch. Never let your succulents sit in water. Do
NOT water on the leaves. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour
off any excess water after a few minutes.
The hotter it is outside, the faster your soil will dry out, so you’ll need to water more often if you live in a hot
area. Water with caution in winter, as the plant can lose its roots if the soil stays cold and wet for extended
periods; protect from frost to prevent scarring.
All of the plants may be shipped bare root.
