Plant Needs
Sunlight
Full direct sunlight is required to maintain a compact, healthy rosette; tolerates partial shade but may become leggy with reduced sun exposure
Watering
Water deeply once every 1–2 weeks during the growing season, allowing the soil to fully dry out between waterings to prevent root rot
Temperature
Tolerates mild frost down to -5°C for short periods; avoid prolonged exposure to temperatures below 0°C or above 40°C
Characteristics
- Leaf: Thick, fleshy triangular leaves with a white gypsum coating, sharp terminal spine, and small, rigid marginal teeth
- Flower: Tall, branched inflorescence bearing yellow, bell-shaped blooms (produced only at the end of the plant’s life cycle)
- Stem: Short, underground caudex with no visible aboveground stem
Care Guide
Watering
Water deeply when the top 10 cm of soil is completely dry
Fertilization
Diluted cactus fertilizer applied once monthly. Avoid fertilizing during winter dormancy; use a low-nitrogen, high-phosphorus feed to promote strong, healthy foliage
Eggshell powder topdress：Crush dried eggshells into a fine powder, then sprinkle lightly on the soil surface once every 3 months; avoid direct contact with leaves to prevent foliar burnPruning
- Remove dead outer leaves at the base of the rosette to maintain a clean, tidy appearance
- Trim the spent flower stalk back to the base after the plant finishes blooming (the parent plant will die following flowering)
- Separate offset pups from the parent plant in spring for propagation, allowing cut ends to callus over for 2–3 days before planting
