Conservatory Greenhouse Houseplants

A small to medium-sized, epiphytic orchid with 25cm long, green, elliptical, leathery leaves. New growth appears from the swollen stem base - pseudobulb, which serves as storage for water and nutrients. They are egg-shaped, compressed at the top. Each pseudobulb carries a single leaf and two or more basal, leaf-bearing sheaths. The plant usually flowers in autumn and winter, on 20-40cm long, pendulous stems carrying many bright, orange-red flowers. Each star-shaped flower is 2.5-4.5cm across.

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 minimum 8°C 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. For more notes on cultivation, see oncidium orchid (cool) cultivation

Propagation

Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided 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.

Suggested planting locations and garden types

  • Houseplants
  • Conservatory and greenhouse

Pruning

No pruning required. Cut off spent flower spikes.

Pests

May be susceptible to mealybugs, aphids and scale insects.

Diseases

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.
