Pot Size: 6"
Accepted Scientific Name: Gymnocalycium baldianum
Origin and Habitat:
Gymnocalycium baldianum is native to the province of Catamarca in northwestern Argentina, where it grows among rocky outcrops and mineral-rich soils at elevations of approximately 500–2,000 metres. The region experiences warm summers, cool winters, seasonal rainfall, and extended dry periods. Adapted to these conditions, this species remains compact while storing water within its globular stem, allowing it to thrive in challenging environments. Its ease of cultivation and exceptional flowering performance have made it one of the most popular Gymnocalycium species worldwide.
Description:
Gymnocalycium baldianum is a small globular cactus typically reaching 3–5 inches tall and 4–6 inches wide. The dark green to blue-green stem is divided into broad ribs with distinct chin-like projections beneath the areoles, a characteristic feature of the genus. Short curved spines provide attractive texture without obscuring the body. Beginning at a relatively young age, plants produce an abundance of spectacular funnel-shaped flowers up to 2 inches across. Blooms range from deep crimson-red and scarlet to magenta and occasionally pink, creating a dramatic display against the dark stem. Its compact size and prolific flowering make it an excellent choice for windowsills, containers, rock gardens, and cactus collections.
Cultivation
Zone: 9–11
Temperature: -5 to 35°C
Growth Rate: Moderate
Soil: Extremely well-draining cactus soil containing pumice, gravel, and mineral aggregates
Watering: Water thoroughly during active growth, allowing soil to dry completely between watering; reduce watering significantly during winter dormancy
Fertilizing: Every 2–3 weeks during active growth using a diluted balanced fertilizer
Light: Bright light to full sun; protect from extreme afternoon heat in very hot climates
Pests and Diseases: Generally resistant; excessive moisture may cause root rot and stem damage
Propagation:
Primarily propagated from seed. Plants flower readily from a young age and often self-pollinate when multiple clones are present.
