Seedling/Propagule
3-6 monthsTiny plantlets with 1-2 leaves and minimal root development. Very fragile and translucent.
Maintain high humidity (80-90%) and warm temps (65-75°F). Provide very bright, filtered light. Water with care to avoid rot. Use sterile, fine orchid mix.
Vegetative Growth
6-12 monthsDevelopment of multiple shoots and leaf rosettes. Narrow, sword-like green leaves emerge from basal crowns. Plant slowly increases in size.
Maintain consistent moisture and humidity. Ensure excellent air circulation with gentle air movement. Feed weekly with diluted orchid fertilizer (1/4 strength). Repot annually in spring.
Pre-Flowering/Budding
2-4 weeksFlowering spikes emerge from leaf axils, with tight, developing buds visible.
Reduce watering slightly to encourage blooming. Maintain cooler nighttime temps (55-60°F) if possible. Continue regular feeding. Avoid moving plant to prevent bud drop.
Flowering
3-6 weeks per inflorescenceDelicate white flowers with purple veining and prominently constricted sepals unfurl. Blooms are long-lasting, typically 3-6 weeks. Flowers have distinctive elongated shape.
Maintain humidity and air circulation without wetting blooms. Keep medium slightly drier than vegetative phase. Avoid temperature fluctuations. Provide bright light to enhance color.
Post-Flowering/Dormancy
2-4 monthsAfter flowers fade, plant enters rest period with focus on vegetative growth and energy storage.
Gradually return to normal watering. Reduce feeding to every 2 weeks. Maintain cool winter temps (55-65°F) for 4-6 weeks to promote reblooming. Resume vigorous growth in spring.
