About
Coelogyne Brymeriana gx is a sizable epiphytic orchid that can reach heights and widths of up to 1 meter. It develops clumps of pseudobulbs, which function as reservoirs for water and nutrients. Each cylindrical pseudobulb typically measures between 25 and 30 centimeters in height and supports a pair of rigid, dark green, lance-shaped leaves. These leaves range from 5 to 10 centimeters in width and can grow up to 70 centimeters long. In spring, the plant produces pendulous stems that can extend from 45 to 70 centimeters, each bearing between 15 and 60 pale cream flowers, occasionally exhibiting yellow-green hues. The flowers, which are star-shaped and approximately 4 centimeters across, showcase pale petals and sepals accented with medium to dark brown markings on the lip. This orchid is classified as a "primary hybrid," resulting from the crossbreeding of two distinct species.
About the genus
Coelogyne is a genus of epiphytic orchids characterized by pseudobulbs that support two leathery, pleated leaves. These plants typically produce flowers in racemes, emerging primarily from the center of new growth during the spring and summer months.

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
