Growth Stages

1

Dormancy

November-February (3-4 months)

Leaves drop from pseudobulbs; plant appears bare and inactive during winter months

Reduce watering significantly but do not allow medium to dry completely. Maintain cooler temperatures (55-65°F) and reduced light. No fertilizing.

2

Sprouting

February-April (6-8 weeks)

New growth emerges from base of pseudobulbs as temperatures warm; leaf development begins

Gradually increase watering and humidity. Resume fertilizing at half strength. Provide bright, filtered light. Keep temperatures 65-75°F.

3

Vegetative Growth

April-August (4-5 months)

Pseudobulbs develop and plump up; new leaves expand, creating lush green foliage

Water regularly; maintain consistent humidity. Fertilize biweekly with orchid fertilizer (diluted). Ensure good air circulation. Stake if needed.

4

Flowering

August-October (2-3 months)

Pendulous or arching flower spikes emerge and develop buds; flowers open sequentially with strong fragrance, typically pink, white, or yellow with purple markings

Maintain consistent warm temperatures and humidity. Continue regular watering. Do not move the plant once spikes develop. Flowers last 2-3 weeks each.

5

Harvest/Enjoyment

Ongoing during bloom season

Flowers at peak fragrance; cut spikes can be used in arrangements or enjoyed on the plant

Leave flowers on plant for maximum visual impact and fragrance in the home. Cut spikes last 1-2 weeks in water if removed.

Companion Planting

Plan your garden →

Plant with:

Other tropical orchids (Cattleya, Dendrobium, Paphiopedilum) Tropical ferns (Asplenium, Platycerium) Bromeliads Pothos or Philodendron (for shared humidity trays)

Avoid planting near:

Dry-climate plants (succulents, cacti) Plants requiring alkaline soil or low humidity Heavy-handed fertilizer feeders that may require different nutrient schedules

Common Pests

  • Increase humidity; spray with water or horticultural oil; isolate affected plants

  • Remove with alcohol-soaked cotton swabs; apply insecticidal soap or neem oil

  • Scrape off manually; treat with horticultural oil or systemic insecticide

  • Improve air circulation; reduce overwatering; remove affected portions; apply fungicide if severe

Harvest Tips

This orchid is not harvested for consumption but enjoyed for its flowers and fragrance. Flower spikes typically appear in late summer through fall. Cut spikes (if desired for arrangements) at the base with sterile pruners once flowers have bloomed; cutting does not harm the plant and may encourage additional spikes next season. Leave flowers on the plant for maximum in-home fragrance experience.

Fun Facts

  • 🌱 Clowesia amazonica exhibits deciduous behavior (leaf drop) as a natural adaptation to dry seasons in its native Amazon habitat, entering dormancy to conserve energy.
  • 🌱 The flower morphology of Clowesia species is so distinctive and unusual that they were historically misclassified; DNA analysis revealed they are closely related to Catasetum orchids, despite their very different appearance.
  • 🌱 The fragrance produced by Clowesia amazonica is strongest in the early morning hours and can change subtly throughout the day, likely evolved to attract specific pollinating insects during peak activity windows.
