Bulbophyllum laxiflorum

Bulbophyllum laxiflorum is a species distributed through Southeast Asia, from Thailand and Malaysia to Sumatra and Borneo. It inhabits warm, humid forests at low to mid elevations, usually growing on tree trunks in shaded areas. The plant forms small pseudobulbs along a creeping rhizome, each with a single leaf. Inflorescences are arching to pendulous, bearing a series of small flowers spaced loosely along the stem rather than in dense clusters. The flowers range in colour from yellow to reddish-orange, often with darker markings, and are adapted for fly pollination. This more open floral arrangement makes it distinct within the genus and a curiosity for orchid growers.

Distinctive Features

• Pseudobulbs and Leaves: Small, clustered pseudobulbs, each bearing a single, leathery, dark green leaf. The leaves are typically 5-8cm long (approximately 2-3 inches) and have a slightly folded appearance.
• Flowers: Produces delicate, translucent flowers that are arranged in a loose, pendant inflorescence. The flowers are typically 1-2cm in diameter (approximately 0.5-1 inch) and have a fascinating structure with a prominent lip and intricate details. The colour can vary from white to cream to pale yellow, often with delicate pink or purple markings.
• Growth Habit: This Bulbophyllum has a sympodial growth habit, meaning it grows horizontally, producing new growths from the base of the previous ones. 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 delicate leaves. An east-facing windowsill or a shaded spot under a grow light is ideal.
• Water: Water regularly, allowing the potting mix to dry slightly between waterings. Avoid overwatering, which can lead to root rot. This orchid prefers a humid environment, so misting the leaves regularly can be beneficial.
• Air Circulation: Good air circulation is crucial for orchids. Ensure that the plant is not placed in a stagnant or enclosed environment. A light breeze or a position near a fan can be beneficial.
• 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 Bulbophyllum can be grown in a pot with a well-draining orchid potting mix. A mix formulated for orchids or epiphytes works well. Repotting is typically done every 1-2 years as needed.
