A medium-sized, epiphytic orchid with strap-shaped, 30-40cm long, evergreen leaves. New growth appears from the swollen stem base - pseudobulb, a storage organ for water and nutrients. Pseudobulbs are oval shaped, slightly flattened around the top and partially covered by one or two pairs of green, leafed sheaths. New flowering stems arise from axils of young mature pseudobulbs and the leafed sheaths. Up to 60cm long, upright flowering stems carry large number of 5cm large, scented flowers. Star-shaped flowers are pale yellow with darker, brow-red markings and white lip

How to Grow

Cultivation

Grow in an open bark-based orchid compost with addition of perlite, sphagnum moss or coir. Provide enough bright filtered light, but keep away from direct sunlight or a heating source. Ideal temperatures are around 13°C minimum at night and up to maximum 25 °C during day. Water regularly, when the pot feels light when lifted. Ensure that all water drains away, preventing the plant sitting wet. Orchid fertiliser can be applied regularly throughout the growing season. Reduce watering and feeding in winter months. The orchid will naturally produce aerial roots, growing outside of 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. For more notes, see oncidium orchid (cool) cultivation

Propagation

Mature plants may be divided when the plant overgrows its container. Each division should have at least 3 older growths with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting

Suggested planting locations and garden types
