About
Paphiopedilum rothschildianum, commonly known as the Gold of Kinabalu orchid or Rothschild's slipper orchid, is a large, clear-leafed species of orchid. It blooms with tall inflorescence of up to six large flowers that are 5-13 inches. It is unique to the Corypetalum group for holding its petals almost horizontally, giving the flower a distinctive appearance. The peak flowering period of this plant is from April to May.
Where it grows
Paphiopedilum rothschildianum is found in the rainforests around Mount Kinabalu in northern Borneo, at elevations between 500 and 1200 meters above sea level. It commonly grows as a terrestrial in ultramafic soil but is also found growing as a lithophyte in leaf-litter on ultramafic cliffs, usually near a river. Paphiopedilum rothschildianum is part of a large number of orchid species endemic to the island of Borneo (more specifically, Kinabalu Park) due to the ultramafic soils which characterize the area and have led to the evolution of many other endemic plant species. Ultramafic soil occurs when high concentrations of elements such as chromium, cobalt, and nickel are found. Paphiopedilum rothschildianum is not restricted to growing in ultramafic soils, but it does seem to account for its success on the island.
