Gymnocalycium marsoneri

A flattened, globular Gymnocalycium of the Gran Chaco and adjacent Andean foothills of northern Argentina, Bolivia and Paraguay. It wants hot, moist summers and a dry, cooler winter, with some shade from the midday sun as it gets under Chaco shrubs.

Where it grows wild

Records come from Chaco lowlands at about 165–850 m and from the foothills of Salta at about 1200–1500 m; like other Chaco Gymnocalycium it is thought to grow among grass and under thorn scrub.

Site elevations range from about 165 m in the Chaco to 1520 m in the Salta foothills.
