Gymnocalycium spegazzinii var. unguispinum is a fascinating variant of the Gymnocalycium spegazzinii species, known for its distinctive claw-like spines and compact, globular form. Native to the arid and rocky regions of Argentina, this cactus features a grayish-green body with pronounced ribs and spines that curve like talons, giving it a unique and rugged aesthetic.
During the blooming season, this cactus produces stunning flowers in shades of pale pink to white, emerging from the crown. Its striking appearance and manageable size make it a sought-after addition to cactus collections.
How to Care
- Light: Thrives in bright, indirect sunlight but can tolerate some direct sunlight. Protect from harsh midday sun to avoid scorching.
- Watering: Water thoroughly but infrequently, allowing the soil to dry out completely between waterings. Reduce watering during winter dormancy.
- Soil: Requires well-draining soil; a cactus mix with added sand or pumice is ideal.
- Temperature: Prefers temperatures between 20°C to 30°C (68°F to 86°F). Keep above 10°C (50°F) and protect from frost.
- Fertilizer: Use a diluted cactus fertilizer during the growing season (spring and summer) to support growth and flowering.
- Repotting: Repot every 3-4 years or when outgrowing its pot. Handle carefully to avoid damaging the roots and spines.
- Propagation: Propagation is typically done by seeds. Offsets are rare but can be used if present.
