Bulbophyllum purpurascens

Bulbophyllum purpurascens is a small orchid occurring from the Himalayan region through Nepal, Bhutan, northeast India, and into Southeast Asia. It inhabits montane forests, often found on tree trunks in moist, shaded environments. The plant produces small pseudobulbs, each with a single narrow leaf. Inflorescences arise at the base and carry umbels of numerous small flowers, typically purple to reddish in colour, occasionally with lighter markings. The clustered floral arrangement is a typical trait in the genus and attracts fly pollinators. Its compact growth and richly coloured flowers make it a valued species for specialist orchid collections.

Distinctive Features

• Pseudobulbs: Small, egg-shaped pseudobulbs that are typically 2-3cm long (approximately 1 inch). Each pseudobulb produces a single leaf.
• Leaves: Leathery, dark green leaves that are typically 10-15cm long (approximately 4-6 inches).
• Flowers: Produces a stunning inflorescence with multiple vibrant yellow flowers. The flowers are typically 2-3cm in diameter (approximately 1 inch) and have a unique, almost hairy texture.
• Growth Habit: This Bulbophyllum has a sympodial growth habit, meaning it grows laterally, producing new pseudobulbs along a rhizome. It is an epiphyte, which means it naturally grows on trees and other surfaces, absorbing moisture and nutrients from the air and rain.

Care Tips

• Light: Bright, indirect light is best. Avoid harsh direct sunlight, which can scorch the leaves. An east-facing windowsill is often ideal.
• Water: Water regularly, allowing the potting mix to dry slightly between waterings. Avoid overwatering, which can lead to root rot.
• Humidity: This Bulbophyllum appreciates 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 warm temperatures between 18-29°C (65-85°F) for optimal growth. Avoid exposing this tropical gem to cold draughts or frost.
• Fertiliser: Use a diluted orchid fertiliser once a month during the growing season (spring and summer). This will help to encourage healthy growth and flowering.
• Potting: This orchid can be grown in pots or mounted on cork bark or tree fern. Use a well-draining orchid potting mix.
