Plant Needs
Sunlight
Full sun to partial shade; tolerates intense arid sunlight, but benefits from light shade in extreme summer heat to prevent leaf scorch.
Watering
Water deeply when the top 10–15 cm of soil is completely dry; avoid overwatering to prevent root rot in poorly drained substrates.
Temperature
Tolerates mild frost down to 5°C; avoid prolonged temperatures below 0°C; thrives in warm, arid or semi-arid climates.
Characteristics
- Leaf: Rosettes of thick, fleshy, grey-green leaves with small teeth along margins; up to 1 m long.
- Flower: Dense, cylindrical racemes of orange-red tubular flowers; nectar-rich for pollinators.
- Stem: Thick, corky, grey-brown trunk with peeling bark; branching with age to form a broad canopy.
Care Guide
Watering
Water deeply when topsoil is fully dry; allow excess water to drain completely
Fertilization
Diluted succulent fertilizer once monthly. Cease fertilization in autumn and winter to support dormancy.
Eggshell powder topdressing：Crush dried, rinsed eggshells into fine powder; sprinkle lightly on soil surface to boost calcium levels and improve soil structure without introducing odors or pests.Pruning
- Remove dead or damaged leaves from rosettes to reduce pest and disease risk.
- Trim spent flower stalks after blooming to redirect energy to vegetative growth.
- Thin overcrowded branches in early spring to improve airflow and maintain a balanced canopy.
