Conservatory Greenhouse Houseplants

An epiphytic, evergreen orchid hybrid; with upright, cane-like, green pseudobulbs. Four to six, dark green, leathery leaves are alternately arranged on the upper half or near the top of each pseudobulb. Each lance-shaped leaf is 8-14cm long and 3cm wide. Upright flowering stems up to 30cm long emerge from the nodes along the mature canes and bear 12-15, occasionally up to 20 flowers opening in succession. Each flower is pale purple 6.5-7cm across, with a darker centre and lip. Sepals are slightly paler in colour than petals.

How to Grow

Cultivation

Plants are best grown in a pot in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. It is a warm-growing orchid and the temperatures should not drop below 16°C. It can be grown similarly to Moth Orchid (Phalaenopsis) but requires much brighter conditions. Provide indirect light and higher humidity by misting regularly in spring and summer, then move the plant to a bright, room in autumn and winter. Water approximately once per week, ensure that roots dry-out between the waterings, especially in winter. See indoor orchid cultivation

Propagation

Propagation by seed is only possible in controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes -remove and pot them into sphagnum moss when the new roots are at least 2cm long.

Suggested planting locations and garden types

  • Houseplants
  • Conservatory and greenhouse

Pruning

No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are at least three, younger, thick, leaf-bearing canes on the plant.

Pests

May be susceptible to scale insects, aphids, mealybugs and red spider mite.

Diseases

Generally disease-free.
