About
Coelogyne ovalis 'Burnham' is an epiphytic orchid that reaches heights of up to 30 cm. It features clusters of green, rounded pseudobulbs, each measuring between 3 to 6 cm tall and 1.5 cm wide, which serve as reservoirs for water and nutrients. From the top of these mature pseudobulbs, two stiff, lanceolate leaves emerge, typically evergreen and measuring up to 15 cm in length and 4 cm in width. Flowering occurs in the autumn to winter months, producing 12 cm long inflorescences that arise from the center of the leaves. The blooms are creamy in color and have a lip adorned with a brown pattern, with each flower reaching about 3 cm in size.
About the genus

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 10°C minimum at night and up to 25 °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
