The Two-Toned Orchid: A Captivating Epiphytic Beauty

Bulbophyllum bicolor is a truly captivating orchid species that hails from the rainforests of Southeast Asia. This unique epiphyte is prized for its unusual two-toned flowers and intriguing growth habit, making it a sought-after addition to any orchid collection.

Distinctive Features

• Pseudobulbs: Small, ovoid 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). The leaves have a prominent midrib and a slightly folded appearance.
• Flowers: Produces a single, captivating flower from the base of the pseudobulb. The flower is typically 5-7cm in diameter (approximately 2-3 inches) and features a striking combination of yellow and red-brown colours. The sepals are often adorned with dark red spots or stripes.
• Growth Habit: This Bulbophyllum has a sympodial growth habit, meaning it grows horizontally, 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 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 help to prevent fungal issues.
• 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 containing bark, sphagnum moss, and perlite is ideal. Alternatively, it can be mounted on a piece of cork bark or tree fern fibre.
