How to grow

Cultivation

Grow in a free-draining orchid mix in a sunny position; water freely when in growth (ideally with rainwater) and sparingly over winter, misting rather than watering to keep just moist. Keep cool but frost free while dormant (1-10°C). Tubers will die after flowering but offsets are produced which will form the next year's plants; repot in spring, discarding any depleted tubers. See indoor orchid cultivation for further advice

Propagation

Propagate by division, separating new bulbs in spring

Suggested planting locations and garden types
  • Conservatory and greenhouse
Pruning

No pruning required; spent stems may be cut back or left to dry naturally

Pests

May be susceptible to fungus gnats, glasshouse whitefly and mealybugs

Diseases

Generally disease-free, though tubers will rot if too moist over winter
