The Gymnocalycium saglionis, commonly called the Giant Chin Cactus, is a large, slow-growing cactus native to Argentina. It forms a round to slightly flattened globe with deep ribs and stout, curved spines. Over time, it can reach impressive sizes compared to other Gymnocalyciums. In summer, it produces showy funnel-shaped flowers, usually white to pale pink, at the crown. Hardy and long-lived, it prefers bright light, well-draining soil, and sparse watering.
