Flowering
2-3 months (blooms sequentially)Delicate, colorful flowers (typically red, orange, or yellow) open along inflorescences; multiple blooms per spike
Maintain high humidity and bright indirect light. Continue watering carefully without splashing flowers. Avoid moving the plant or exposing to temperature stress. Flowers last 2-4 weeks per bloom.
Post-Bloom Rest
4-8 weeksFlowers fade and drop; plant redirects energy to growth and root development
