Gymnocalycium anisitsii var. tucavocense

Morphological Characteristics

Gymnocalycium anisitsii var. tucavocense is a charming and uncommon variety of the anisitsii species complex, prized for its small, globular shape and soft spination. It features a flattened, ball-shaped body that ranges from deep green to olive-green, often with a slightly glossy texture.

The body typically shows 10–13 shallow ribs, each marked by small, rounded tubercles. From these arise short, thin spines—usually 5 to 7 radial spines per areole and sometimes a single central spine. These spines are pale gray to pinkish-white, fine and flexible, giving the plant a delicate, brush-like appearance.

When in bloom, this species produces eye-catching flowers that are pale pink to near-white, sometimes with a subtle darker mid-stripe. Flowers are relatively large compared to the body and appear from the plant’s apex during spring or early summer.

Growth Habits

This cactus remains compact and non-offsetting for a long time but may eventually produce basal pups in maturity. It is relatively fast-growing for a Gymnocalycium and can fill a small pot within a few seasons.

Ideal for windowsill culture, desktop containers, or cactus groupings, it performs best in filtered sunlight and slightly shaded environments.

Maintenance Points

• Lighting: Prefers bright but indirect sunlight. Morning sun is ideal; avoid harsh midday rays in hot climates.

• Watering: Water when soil is completely dry. During winter dormancy, reduce watering to once every 4–6 weeks.

• Soil: Use a well-draining cactus mix. Enrich with pumice or perlite to prevent water retention.

• Temperature: Optimal range is 18–30°C (65–86°F). Not frost-hardy; protect below 5°C (41°F).

• Fertilization: Apply a diluted cactus fertilizer once a month during spring and summer. Avoid feeding in winter.

• Handling: Easy to handle due to soft spines. Ideal for homes with pets or children, though care is still recommended.

• Pests: Occasionally susceptible to mealybugs and root rot if overwatered or kept in poor ventilation.
