About
This large-sized evergreen orchid, producing a clump of ovoid, up to 10cm long pseudobulbs. Flowers are approximately 4cm large, with dark maroon petals and sepals and white lip with burgundy-purple spots and yellow ridge in the centre. Pendant flowerings stems up to 75cm long, carrying 10-30 flowers emerge from the base on young pseudobulbs in summer. The pseudobulbs are covered with leaf bases, each carrying 7 to 9, semi-rigid, linear leaves 50-90cm long and 1.5-4cm wide.
About the genus
Cymbidium are epiphytic, lithophytic or terrestrial orchids with prominent spherical to ovoid pseudobulbs, long linear leaves and fleshy white roots. Several long lasting showy flowers with a distinctive 3-lobed lip are borne on erect or arching flower spikes from the bases of the pseudobulbs

Care notes
CultivationGrow 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.
PruningNo pruning required. Cut down flowered stems to base.
PropagationPropagation 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 resistanceMay be susceptible to aphids, glasshouse red spider mite, scale insects and mealybugs
Disease resistanceGenerally disease-free. Sterilising cutting tools may prevent virus diseases, such as Cymbidium Mosaic Virus (CMV).
