About
Bulbophyllum echinolabium is an epiphytic orchid that thrives in warm to hot conditions, typically found clinging to the branches and trunks of trees in humid forest environments near rivers. This species features bulbous, egg-shaped structures known as pseudobulbs, which serve as reservoirs for water and nutrients. These pseudobulbs arise from a creeping, rooting stem that anchors the plant to the tree bark. Each pseudobulb produces a single, club-like leaf at its apex. The orchid blooms with individually occurring flowers, which are pale pink with fine stripes and emit an unpleasant odor. These flowers, the largest within their genus, appear on a stem that can reach lengths of up to 70 cm, blooming successively from spring through summer. Notably, the flowers have a warty, moveable lip that is reddish-purple, a unique adaptation designed to attract pollinators.
About the genus
This genus encompasses a broad range of primarily epiphytic, sympodial tropical orchids. These plants form clusters of small pseudobulbs that function as reservoirs for water and nutrients. Typically, each pseudobulb supports a single leaf. There are more than 2,000 recognized species within this group.

Care notes
- Cultivation
- Grow in an open, well drained but moisture-retentive mix of medium orchid bark, sphagnum moss and perlite. Shallow, wide pots or baskets are best used to accommodate its spreading habit. Bright filtered light is best as direct sunlight through glass can scorch its leaves. Prefers a minimum night temperature of 15°C and a maximum of 30°C in the daytime. Nighttime temperatures should be 10°C lower than daytime temperatures for good growth and is beneficial to induce flowering. High humidity is required along with gentle air movement. Allow plants to freely drain when watering and avoid plants sitting in water as this can cause roots to rot. Plants may be intolerant of hard tap water, so irrigate with rainwater at room temperature. Orchid fertiliser can be applied regularly throughout the growing season, March to September. Reduce watering and feeding in winter months. See indoor orchid cultivation for further advice
- Pruning
- No pruning required. Remove spent flower stem at the base
- Propagation
- Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting
- Pest resistance
- May be susceptible to mealybugs and scale insects
- Disease resistance
- Generally disease-free
