Clowesia orchids are deciduous epiphytic orchids native to Central and South America, known for their fragrant, waxy flowers that range from white to yellow and pink. These orchids have a distinct growth habit, producing tall, leafy pseudobulbs during the growing season followed by a pronounced dormant period. They are prized by collectors for their elegant, fragrant blooms and relatively robust nature compared to other orchids.

Growth Stages

1

Dormancy

2-3 months

Plant enters deciduous dormancy in late fall-early winter, dropping leaves from pseudobulbs; pseudobulbs appear bare and withered

Drastically reduce watering; provide cooler temperatures (55-60°F); minimal fertilization; maintain humidity but allow medium to dry out more

2

Budbreak & Flowering

4-8 weeks

New flower spikes emerge from base of pseudobulbs in late winter-early spring; fragrant flowers open in succession

Resume moderate watering as buds form; maintain warmth (65-75°F); provide bright light; do not move plant during this critical phase

3

Vegetative Growth

4-6 months

New leaves and tall pseudobulbs develop through spring and summer; plant is lush and actively growing

Water regularly; fertilize every 2 weeks with diluted orchid fertilizer; maintain warmth (70-80°F) and humidity; increase light gradually

4

Maturation

2-3 months

Pseudobulbs reach full size and foliage matures; plant begins to slow growth in late summer-fall

Maintain consistent care but reduce fertilizer gradually; provide slight temperature drop (5-10°F cooler nights); continue adequate watering

5

Preparation for Dormancy

2-3 weeks

Plant begins dropping leaves; growth slows significantly; pseudobulbs firm up and mature

Gradually reduce watering; stop fertilizing; provide cooler temperatures and drier conditions; reduce watering frequency to prepare for dormancy

  • Increase humidity; spray with water mist; use miticide if infestation is heavy; ensure good air movement

  • Hand-remove with soft brush; apply horticultural oil or neem oil; repeat treatment every 7-10 days

  • Improve drainage and air circulation; reduce humidity if present; remove affected portions; apply fungicide if necessary

Clowesia orchids are ornamental plants grown for flowers rather than harvest. Cut flower spikes with sterile pruners once blooms open; stems can last 2-3 weeks in water. Allow flowers to fully develop on the plant for 1-2 weeks before cutting to ensure optimal fragrance and longevity.
