Growing details
Sunlight
Bright, indirect light for 6 to 8 hours daily; avoid direct sun exposure which can scorch the foliage.
Watering
Water thoroughly whenever the top inch of soil feels slightly dry, utilizing filtered or distilled water to avoid mineral buildup on the leaves.

Rarely flowers indoors; when grown in optimal tropical greenhouses, it produces small, insignificant yellow or white tubular flowers.
Propagation
Propagated primarily through root division during the spring repotting season by gently separating established clumps with intact roots and rhizomes.
Common pests & issues
Prone to spider mites and fungus gnats if humidity is too low or soil remains overly saturated; brown leaf tips often indicate low humidity or chemical sensitivity in tap water.
