Plant Needs
Sunlight
Requires full direct sunlight for vibrant leaf color and healthy growth; tolerates partial shade in extreme heat but may lose blue pigmentation
Watering
Water deeply only when the top 15–20 cm of soil is completely dry; avoid overwatering to prevent root rot in poorly drained media
Temperature
Thrives in 18–30°C; tolerates brief light frosts down to 5°C but requires protection from prolonged freezing temperatures
Characteristics
- Leaf: Thick, fleshy blue-green linear leaves with sharp terminal spines and rigid marginal teeth
- Flower: Yellow, bell-shaped blooms in dense branching panicles on tall, woody stalks
- Stem: Short, compact basal stem obscured by overlapping leaf bases
Care Guide
Watering
Water deeply every 10–14 days when soil is fully dry
Fertilization
Diluted low-nitrogen feed once every 2 months. Use fertilizer with balanced potassium and phosphorus to support leaf structure and water storage
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle lightly on soil surface every 3 months to add calcium without raising nitrogen levelsPruning
- Remove dead or damaged outer leaves at the base to maintain rosette shape and improve airflow
- Trim the tall flowering stalk after blooms fade (the parent plant will die post-flowering)
- Separate offset pups in spring for propagation; allow cut surfaces to callus before planting
