Bulbophyllum longissimum

The Miniature Orchid with Rapunzel Roots

Bulbophyllum longissimum is a truly enchanting miniature orchid species that hails from the rainforests of Southeast Asia. This unique epiphyte is prized for its unusual growth habit, long, trailing roots, and captivating flowers, making it a delightful addition to any orchid collection.

Distinctive Features

• Roots: Perhaps the most striking feature of this orchid is its long, wiry roots that can grow up to 1 metre (approximately 3 feet) in length! These trailing roots are covered in tiny, silvery hairs that help the plant absorb moisture and nutrients from the air.
• Pseudobulbs and Leaves: Small, clustered pseudobulbs, each bearing a single, fleshy, dark green leaf. The pseudobulbs are typically 1-2cm in diameter (approximately 0.5-1 inch), while the leaves are 3-5cm long (approximately 1.5-2 inches).
• Flowers: Produces clusters of small, fragrant flowers that are typically yellow or orange with red markings. The flowers are about 1cm in diameter (approximately 0.5 inches) and have a unique, spicy fragrance.
• Growth Habit: This Bulbophyllum has a creeping, rhizomatous growth habit. It thrives when mounted on a piece of cork bark or tree fern fibre, allowing its long roots to trail freely.

Care Tips

• Light: Bright, indirect light is best. Avoid harsh direct sunlight, which can scorch the delicate leaves.
• Water: Water frequently, ensuring that the roots are kept moist but not soggy. Misting the roots daily is often beneficial.
• Humidity: This Bulbophyllum appreciates high humidity. You can increase humidity by using a humidifier, placing the plant on a humidity tray, or misting the roots and leaves regularly.
• Temperature: Maintain warm temperatures between 18-29°C (65-85°F) for optimal growth. Avoid exposing this tropical gem to cold draughts or temperatures below 15°C (59°F).
• Fertiliser: Use a diluted orchid fertiliser once a month during the growing season (spring and summer).
• Mounting: Mount this Bulbophyllum on a piece of cork bark or tree fern fibre, allowing the roots to attach and trail freely. This mimics its natural epiphytic growth habit.

Additional Notes

• Bulbophyllum longissimum is a fascinating and rewarding orchid to grow. Its unique growth habit and captivating flowers make it a true conversation starter.
• This orchid can be propagated through division, carefully separating the rhizome and ensuring that each division has at least one pseudobulb and a healthy root system.
• With proper care, your Bulbophyllum longissimum will thrive and bring a touch of the exotic to your home. Enjoy its unique beauty and the fascinating world of orchids!
