Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water moderately during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly as the foliage begins to yellow and die back in late spring or early summer.
Ensure good drainage to prevent bulb rot. Water sparingly during dormancy.
Remove faded flower stalks after blooming to prevent seed formation and direct energy back into the bulb. Cut back the foliage only after it has completely yellowed and died down naturally in late spring or early summer.
Do not cut green leaves prematurely.
Propagate by offsets (bulblets) that form around the parent bulb. Carefully separate these bulblets during repotting in late summer or early autumn. Plant them at the same depth as the parent bulb.
Seed propagation is also possible but slower.
Repot every 2-3 years or when the bulbs become overcrowded. The best time for repotting is in late summer or early autumn when the bulbs are dormant. This allows for inspection and separation of offsets.
Use fresh, well-draining potting mix.
