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
