Bulbophyllum mirum
release_alert Low Stock - 2 available
Bulbophyllum mirum is an orchid found from peninsular Malaysia through Sumatra and Borneo. It grows in humid, shaded forests, usually at low to mid elevations. Plants form small pseudobulbs, each with a single narrow leaf. The inflorescences are short, carrying umbels of numerous small flowers coloured orange-brown to reddish, with sepals often fringed or lined with fine hairs. The unusual structure of the flowers is adapted for fly pollination, a hallmark of the genus. Its compact growth and distinctive blooms make it a sought-after species for specialist collections.
Distinctive Features
- Pseudobulbs: Small, roundish pseudobulbs that are typically 1-2cm in diameter (approximately 0.5-1 inch). These pseudobulbs store water and nutrients, allowing the plant to thrive in its epiphytic lifestyle.
- Leaves: Each pseudobulb produces a single, leathery leaf that is typically 5-10cm long (approximately 2-4 inches). The leaves are dark green and have a slightly succulent texture.
- Flowers: Produces clusters of small, intricately detailed flowers that are typically reddish-brown in colour. The flowers have a unique, musky fragrance that attracts ants.
- Growth Habit: This Bulbophyllum has a creeping rhizome from which the pseudobulbs emerge. It naturally grows on trees, clinging to the bark with its roots. It can be grown mounted on cork bark or in a hanging basket with a well-draining epiphyte mix.
- Ant Symbiosis: This orchid has evolved specialised hollow pseudobulbs that provide shelter for ants. The ants, in turn, protect the plant from pests and provide nutrients through their waste.
Care Tips
- Light: Bright, indirect light is best. Avoid harsh direct sunlight, which can scorch the leaves.
- Water: Water regularly, allowing the potting mix to dry slightly between waterings. Avoid overwatering, which can lead to root rot.
- Humidity: This Bulbophyllum appreciates moderate to high humidity. You can increase humidity by using a humidifier, placing the plant on a pebble tray filled with water, or misting the leaves regularly.
- Temperature: Maintain intermediate to warm temperatures between 18-29°C (65-85°F) for optimal growth.
- Fertiliser: Use a balanced orchid fertiliser, diluted to half strength, every 2-4 weeks during the growing season.
- Air Circulation: Good air circulation is essential to prevent fungal issues. Ensure the plant is in a well-ventilated environment.
