About
Coelogyne pulverula is a robust epiphytic orchid that can reach heights and widths of up to one meter. It features a cluster of green, elongated pseudobulbs that function as reservoirs for moisture and nutrients. Each mature pseudobulb supports a pair of stiff, dark-green leaves, which measure between 25 to 70 centimeters in length and 4 to 11 centimeters in width. In spring, this orchid typically produces pendulous inflorescences that can extend up to one meter, showcasing as many as 60 flowers arranged approximately 2.5 centimeters apart. Each flower measures around 4 centimeters in diameter, exhibiting a creamy hue accented by a dark-brown pattern on its white lip.

Care notes
- Cultivation
- Grow in an open, free-draining, bark-based orchid mix. Provide enough bright filtered light, but keep away from direct sunlight or a heating source. Ideal temperatures are around 16 °C minimum at night and up to 28 °C during the day. Water regularly, when the pot feels light when lifted. Ensure that all water drains away, preventing the plant from sitting wet. Orchid fertiliser can be applied regularly throughout the growing season. Reduce watering and feeding in winter months. The orchid will naturally produce rhizomes with aerial roots growing outside the pot. As with many orchids, they grow best when well-established and slightly pot-bound. Re-potting should be only done if the plant overgrows its container or before the potting mix starts to deteriorate - approximately once in 2-3 years. See indoor orchid cultivation for more tips
- Pruning
- No pruning required other than removing spent flower stems
- Propagation
- Propagation by seed is only possible in a controlled laboratory environment. Well-established plants can be propagated by division. Ensure each division has young enough, mature pseudobulbs to support new growth
- Pest resistance
- May be susceptible to scale insect and mealybugs. Thrips can cause damage on flowers and developing flower buds
- Disease resistance
- Generally disease-free. Poor air movement may cause bacterial or fungal rots. Good hygiene practice and sterilising cutting tools prevent the spread of virus diseases
