Gymnocalycium horstii – Spindelkaktus, sällsynt kaktus med spektakulära taggar och stora blommor

Gymnocalycium horstii, also known as Spider Cactus, is a globular cactus native to southern Brazil, much loved by collectors for its unique appearance. The spherical, glossy green stem, marked by deep ribs, is covered with large areoles from which long, curved spines emerge, resembling spider legs. When mature, it produces large, striking flowers in shades from pale pink to white, which open during the day and create an elegant contrast with the plant’s dark green body.
