Paphiopedilum rothschildianum

Paphiopedilum rothschildianum or Rothschild’s slipper orchid is a mythical orchid from Borneo.

It is threatened because it is even rare in its very limited natural habitat, deforestation and illegal picking for the black market where the plant costs up to 5,000 USD, earning it the reputation of being the most expensive orchid in the world. Plants from reputed growers are found at around 100 USD though.

The Rothschild slipper orchid appears in the Penny Dreadful series, in the Palm House of Kew Gardens.

Care is easy but growth is slow: it takes 15 years for the plant to start blooming.

It is widely used for the production of hybrids because of its beautiful flowers.

It belongs to the family Orchidaceae, sub-family Cypripedioideae, genus Paphiopedilum.


Paphiopedilum rothschildianum is a terrestrial, sometimes lythophytic orchid.

The leaves are bright green, up to 60 cm long and 4.5-7.5 cm wide.

The inflorescence is 45 cm long, reddish and carries 3-6 flowers. The petals are triangular at the top and bright yellow green with almost black longitudinal stripes. The dorsal sepal is about 6.5 cm tall and 3.5-4.5 cm wide, oval, pointed, yellowish with numerous very dark, almost black longitudinal stripes and white margins. The synsepalum is about 5.5 cm long. The spread, elongated petals are almost horizontal, 10-14 cm long and 1 cm wide, green yellow with dark spots around the base and dark stripes. The lip is bag-shaped, somewhat laterally compressed, protruding, 4.5-5.8 cm tall and 2.2 cm wide, cinnamon-colored with vermilion around the mouth. The staminode is particularly shaped and resembles the head and beak of a crane bird, with a long 2-toothed apex. It is hairy at the base and along the margins.

Size and flower color may vary. Smaller plants usually have more deep-colored, better-formed flowers.
