Paphiopedilum rothschildianum

<em>Paphiopedilum</em> <em>rothschildianum</em> John Fielding
Conservatory Greenhouse Houseplants Herbaceous Perennial

A medium to large-sized, clump-forming, evergreen tropical orchid. Linear, glossy, bright green leaves are up to 60cm long and 5cm wide. Flowering stem up to 75cm long appears from the centre of the leaf rosette and carries 2 to 4 large, glossy flowers. The pouch is a modification of the lip that traps insects and consequently provides an ''escape route'' that results in pollen collection and flower pollination. Lateral sepals are fused, pale cream with brown stripes, almost identical with upper, dorsal sepal. The petals are thin, very long and almost horizontal, pale green or yellow with brown stripes and small spots with tiny brown hairs.

How to Grow

Cultivation

Grow in terrestrial, bark based orchid mix, with added sphagnum moss and perlite, or crushed limestone chips. In summer, provide higher humidity and bright, filtered light. Average summer temperatures are between 20 - 25°C, with winter temperatures falling to 18 - 22°C. Apply fertiliser with every third watering. Avoid heavy misting or overhead watering. As the plant lacks pseudobulbs, it shouldn't be left dry for long time. Water plant as it approaches dryness, but avoid standing in water, or keeping wet for prolonged period. See Paphiopedilum cultivation for more detailed advice.

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 healthy, rooted plant rosettes with a suffient 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. Remove the flower stem after flowering.

Pests

May be susceptible to mealybugs but generally pest-free.

Diseases

May be susceptible to bacterial rots in the centre of leaf rosettes caused by overhead watering in combination with low temperatures but generally disease-free
