Dormancy/Dry Season
September-NovemberPlant sheds leaves and growth slows; rhizomes may shrivel slightly
Minimize watering, provide bright light, maintain cool temperatures (55-65°F), ensure excellent air circulation
Vegetative Growth
December-AprilNew shoots emerge with large, lanceolate leaves; plant produces new pseudobulbs
Water regularly and thoroughly, maintain humidity above 60%, feed bi-weekly with diluted orchid fertilizer, provide warm temperatures (70-80°F)
Flowering
January-March (4-6 weeks per flower)Inflorescences emerge from base of pseudobulbs, producing 1-6 fragrant, swan-shaped flowers; blooms are typically yellow to cream with spotted markings
Support inflorescences with stakes if needed, maintain high humidity, avoid moving plant, continue regular watering, provide good air circulation
Post-Flowering Decline
April-SeptemberFlowers drop, plant gradually reduces growth, leaves begin to yellow
Gradually reduce watering frequency, maintain bright light, lower humidity slightly, begin transitioning to dry season conditions

Harvest Tips
Cut flower sprays for arrangements when 1-2 blooms are fully open; flowers last 2-3 weeks in a vase if kept cool and in fresh water changed every 2-3 days. For propagation, divide pseudobulbs when repotting; each division should have at least 3-4 mature bulbs.
Fun Facts
- 🌱 The Swan Orchid's flower shape varies between male and female flowering forms on the same plant—the 'male' flowers point upward like a swan's neck, while 'female' flowers are more pendant and cup-shaped.
- 🌱 Cycnoches ventricosum is deciduous and requires a distinct dry season to flower; plants that don't receive this dormancy period often fail to bloom, making seasonal discipline crucial for success.
- 🌱 The genus Cycnoches is pollinated exclusively by male orchid bees (Euglossini) in their native habitat; the flowers produce fragrant compounds the bees collect and use in elaborate mating displays, making this one of nature's most sophisticated pollination strategies.
