It is a globose cactus, spherical or a little flat, with a diameter up to 8 cm, dark green in colour, or sometimes brown. It has 8 to 10 ribs with tubercle-shaped areoles, covered in groups of 6 to 8 pale grey, curved spines, giving to the species its common name of spider-cactus. Like many cacti, it does not divide but may form offsets after some years. The funnel-shaped flowers reach a diameter of 6 cm, growing near the apex of the plant and are red, pink or orange.
Gymnocalycium baldianum is easy to grow. It needs a well-drained soil. In summer, water the plants well, but let them to dry before watering again. Use monthly a fertilizer for cacti. In winter, keep it dry, and the temperature may be as low as −10 °C (14 °F), but it is better to keep it without frost. The exposure must be sunny in summer and at least brightly lit in winter.
