About
Cymbidium Gwen Sherman gx is a medium to large evergreen epiphytic orchid characterized by clusters of egg-shaped pseudobulbs that feature basal sheaths adorned with leaves. The linear leaves are semi-rigid, reaching lengths of up to 90 cm and widths of about 2 cm. In late winter and spring, mature pseudobulbs send forth arching flower spikes that can extend up to 90 cm. Each inflorescence may host as many as twenty flowers, each measuring around 8 cm across, with colors that vary by cultivar, including waxy hues of white, cream, pale pink, or pale yellow.
About the genus
Cymbidium species are orchids that can grow as epiphytes, lithophytes, or terrestrial plants. They feature noticeable spherical to ovoid pseudobulbs, elongated linear leaves, and thick white roots. These orchids produce multiple long-lasting flowers, characterized by a unique three-lobed lip, which emerge from erect or arching spikes at the base of the pseudobulbs.

Care notes
- Cultivation
- Grow in an open, free-draining orchid compost with addition of perlite, sphagnum moss or coir. Requires day temperatures around 16°C and 10°C at night. Provide good light levels, but avoid direct sunlight. Water plants thoroughly when compost is almost dry, allow to drain and use orchid fertiliser regularly during growing season. Reduce watering in winter. Place outside in dappled shade during the summer months to aid flower initiation. See cymbidium cultivation for more detailed information
- Pruning
- No pruning required. Cut down flowered stems to base
- Propagation
- Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided in early or mid spring, 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 aphids, glasshouse red spider mite, scale insects and mealybugs
- Disease resistance
- Generally disease-free. Sterilising cutting tools may prevent virus diseases, such as Cymbidium Mosaic Virus (CMV)
