Plant Needs
Sunlight
Thrives in full sun to partial sun; tolerate intense desert sunlight, but avoid prolonged deep shade which can cause leggy growth
Watering
Allow soil to dry completely between waterings; avoid overwatering to prevent root rot, especially in cool, humid conditions
Temperature
Hardy to mild frost; protect from temperatures below 5°C to prevent leaf damage, and thrive in warm, dry desert-like conditions
Characteristics
- Leaf: Thick, rigid dark green leaves with crisp white marginal lines and a sharp terminal spine, arranged in a symmetrical rosette
- Flower: Tall, 3–6 m flowering spike with tubular yellow flowers (rarely produced in cultivated specimens)
- Stem: Short, subterranean stem hidden beneath overlapping leaf bases
Care Guide
Watering
Water deeply once every 1–2 weeks, allowing soil to dry fully between waterings
Fertilization
Apply diluted, low-nitrogen cactus fertilizer once every 2 months. Do not fertilize in autumn or winter when growth slows
Dried eggshell powder topdress：Crush dried, rinsed eggshells into a fine powder and sprinkle a thin layer on the soil surface to boost calcium levels and improve drainage; avoid overapplication to prevent soil alkalinityPruning
- Remove dried, brown outer leaves to maintain a tidy rosette shape
- Trim the dead flower spike after blooming (note: the parent plant will die after flowering, but offsets can be propagated)
- Avoid handling leaves directly to prevent punctures from sharp terminal spines
