Gymnocalycium Ragonesei seeds pack of 8 seeds

Gymnocalycium Ragonesei Origin and Habitat: Gymnocalycium ragonesei has a very restricted range in Catamarca (and Cordoba?), Argentina (extent of occurrence is less than 100 km2).
Altitude: It grows at low elevation of 100 to 200(-400) metres above sea level.
Habitat and Ecology: Gymnocalycium ragonesi grows semi-buried at the edge of saline grasslands. The concentration of salts is high in the surface of the ground, but it decreases deeper down where the roots grow. The major threat for this species is illegal collection. It grows together with Gymnocalycium schickendantzii, Gymnocalycium asterium v. paucispinum and Setiechinopsis mirabilis.
