Bulbophyllum plumatum

Bulbophyllum plumatum is a miniature epiphytic orchid native to Southeast Asia, particularly found in the Philippines (notably Luzon and Mindanao) and parts of Malaysia. This orchid is very small, making it perfect for terrariums where space and humidity can be carefully controlled.

Features:

• Size: Compact, with pseudobulbs approximately 1–2 cm long, topped by a single, leathery leaf typically 5–10 cm long and 1–2 cm wide.

• Flowers: Each inflorescence emerges from the base of a pseudobulb and forms a small, umbrella-like cluster (umbel) of 3–7 flowers. Individual flowers are tiny—about 1–2 cm wide—but striking:

  • Appendages: The standout feature is the long, feathery structures extending from the sepals, giving the flower a wispy, feathered look. These can be up to 10 cm long, adding dramatic flair.

  • Lip: The tiny lip is mobile and hinged, often purple or reddish, designed to attract pollinators through slight vibrations in the breeze.

  • Fragrance: Reports vary, but it’s typically mild or faintly sweet—not one of the foul-smelling Bulbophyllum species known for mimicking carrion.

Care Tips:

• Light: Prefers low to moderate, indirect light (800–2,000 foot-candles). It thrives in shade or filtered sunlight, avoiding direct burn.

• Temperature: Warm to intermediate, 18°C–29°C (65°F–85°F) during the day, with a slight drop at night. It’s sensitive to cold below 13°C (55°F).

• Humidity: High, 70%–90%. It thrives in terrariums, greenhouses, or with regular misting.

• Watering: Keep the medium (e.g., sphagnum moss, bark, or mounted on cork) consistently moist but not soggy. Good air circulation prevents rot.

• Air Movement: Essential to mimic its breezy forest home and keep the fine roots healthy.

• Fertilizer: Light feeding (e.g., 1/4 strength orchid fertilizer) every 2–4 weeks during the growing season.
