Bulbophyllum spp.

flower

Bulbophyllum is a large genus of epiphytic orchids native to tropical regions, characterized by distinctive pseudobulbs and unique, often fragrant flowers that range from tiny to medium-sized. These orchids are prized by collectors for their unusual flower shapes, colors, and sometimes unpleasant scents that attract pollinators in their native habitats. They represent one of the most diverse orchid genera with thousands of species and hybrids.

Growth Stages

1

Seedling/Plantlet

6-12 months

Tiny orchid with emerging leaves and minimal pseudobulb development; very fragile and slow-growing

Maintain high humidity (70-90%), bright indirect light, and keep medium consistently moist; use small pots with fine orchid bark mix; protect from direct air movement

2

Vegetative Growth

1-3 years

Development of pseudobulbs and leafy stems; plant gradually increases in size and vigor; new growth emerges from rhizomes

Provide warm temperatures (65-80°F), bright indirect light, and regular watering during active growth; fertilize monthly with diluted orchid fertilizer; increase pot size when plant fills current container

3

Maturation

Ongoing until flowering

Plant reaches blooming size with well-developed pseudobulbs and established root system; foliage is healthy and robust

Maintain consistent warm conditions; provide slight temperature drop in winter (55-65°F) to trigger flowering; reduce watering in winter rest period; ensure excellent air circulation

4

Flowering

2-12 weeks depending on species

Distinctive flowers emerge from base of pseudobulbs or along stems; flowers may be fragrant (pleasant or fetid), colorful, or unusual shapes; blooms may last weeks to months

Maintain high humidity and air circulation; continue appropriate watering; avoid moving plant during bloom; some species require cooler winter rest to initiate flower buds; avoid fertilizer changes that may cause bud drop

5

Post-Bloom Rest

4-8 weeks

Flowers fade and drop; plant may enter semi-dormant period with reduced growth; pseudobulbs gradually dry

Reduce watering but don't allow medium to dry completely; lower temperature slightly (55-65°F); reduce fertilizer; maintain humidity; allow rest period of 4-8 weeks before resuming regular care and warmth

Common Pests

  • Increase humidity, mist foliage regularly, spray with neem oil or insecticidal soap if infestation occurs

  • Remove with cotton swab dipped in rubbing alcohol; spray affected areas with insecticidal soap; repeat weekly until pest is eliminated

  • Manually remove with brush or swab; treat with horticultural oil or neem oil spray; inspect regularly for reinfestation

  • Allow top of medium to dry between waterings; use yellow sticky traps; apply sand layer on medium surface to prevent egg-laying

  • and

    Improve air circulation, reduce humidity slightly, avoid overhead watering, remove affected tissue with sterile tools, use fungicide if necessary

Fun Facts

  • 🌱 Bulbophyllum contains over 2,000 species, making it one of the largest genera in the orchid family (Orchidaceae), yet remains relatively unknown outside of serious orchid collector communities
  • 🌱 Many Bulbophyllum species produce flowers with a distinctive fetid smell resembling rotting flesh or feces, a strategy that attracts carrion flies and other insects for pollination rather than relying on bees or butterflies
  • 🌱 The genus name 'Bulbophyllum' refers to the distinctive pseudobulbs (bulb-like structures) that store water and nutrients, with 'phyllum' meaning leaf, as flowers and leaves often emerge from these specialized stems
