New Growth
3-4 monthsEmerges from base of mature pseudobulb; new shoot develops several leaves and a small pseudobulb begins to form
Maintain consistent warmth (70-80°F), bright light, and regular watering; support new growth with misting and humidity
Pseudobulb Maturation
4-6 monthsNew pseudobulb enlarges and hardens; foliage fully develops with 2-3 lanceolate leaves reaching 12-18 inches long
Continue bright, filtered light and regular watering; apply balanced orchid fertilizer every 2 weeks during active growth
Rest/Dormancy
6-8 weeksPlant slows growth; leaves may show slight color change; inflorescence bud develops at base of pseudobulb
Reduce watering significantly; lower night temperatures to 55-65°F; reduce fertilizer; maintain lower humidity
Blooming
4-6 weeksFlower spike emerges and develops 1-4 large violet-purple flowers with dark magenta labellum; flowers are fragrant and long-lasting
Maintain bright, indirect light; avoid moving plant; support spike with stake if needed; cease fertilizing; enjoy flowers for 4-6 weeks
Post-Bloom
Ongoing cycleFlowers fade and drop; plant begins new growth cycle from base of bloomed pseudobulb
Resume moderate watering and fertilizing; remove spent flower spike; begin next growth cycle management

Harvest Tips
This is a flowering ornamental orchid, not harvested for consumption. Cut flowers for arrangements by sterilizing blade and cutting the flower spike above the node (joint) to allow potential reblooming. Flowers last 4-6 weeks on the plant or 2-3 weeks in a vase. Do not deadhead—leave spent flowers to signal the plant to initiate next bloom cycle.
Fun Facts

- 🌱 The flowers are notably fragrant, producing a sweet scent that intensifies in the morning hours when natural pollinators (orchid bees) are most active in their native habitat.
- 🌱 This species was one of the foundational plants used in the early years of Cattleya orchid hybridization in Victorian England, and its genetics remain important in modern hybrid development.
