Shape
Please note that each plant is unique, and the crested shape may differ to some extent from the photos.
Where it grows
The non-crested natural form of Gymnocalycium anisitii is native to South America, specifically to Bolivia.
Special features
This unique Gymnocalycium has a stem that contorts in on itself along the central growth point, giving it a jagged appearance. These particular specimens are almost monstrose in appearance, with the crest appearing to grow mainly in the middle of the stem of the plant.
Care Guide
Gymnocalycium is an easy cactus to care for, though care should be taken to not expose the crested form to frost. This plant can handle full morning sun, and will enjoy a sunny spot in a cactus greenhouse. Plant it in a gritty and well-aerated soil mix that allows for free drainage of water. Water it well in the spring and summer growing season, but keep dry in winter. Do not water on top of the stem, as any water stuck in the crested portion will cause stem rot.
Growing season
Spring and summer.
