About
Spathoglottis plicata, commonly known as the Philippine ground orchid, or large purple orchid is an evergreen, terrestrial plant with crowded pseudobulbs, three or four large, pleated leaves and up to forty resupinate, pink to purple flowers. It is found from tropical and subtropical Asia to Australia and the western Pacific including Tonga and Samoa.
How to grow it
Spathoglottis plicata and its varieties have been cultivated and selected. The typical one has a bright purple flower. Some of them have mauve or pale mauve flowers. The rare pure white form is called ‘Penang White’. Due to its hardiness and fast growth, Spathoglottis plicata is cultivated and used in hybridizing with other mountain Spathoglottis that are difficult to grow in the lowland to produce more interesting varieties. The first Spathoglottis hybrid was produced in 1932 by Richard Eric Holttum who crossed S. plicata with S. aurea and gave it the name Spathoglottis 'Primrose'. ‘Dwarf Legion’ is a hybrid of 'Primrose' and S. tomentosa, a dwarf form that produces many colours of flower, from pink to yellow, and pure cream.
Spathoglottis plicata needs to be grown in well-drained, well-aerated soil with the upper part of the ‘bulb’ above the ground level. Dilute manure water applied frequently is recommended.
Where it grows
The large purple orchid is found in Taiwan, southern India, Indonesia, Japan, Malaysia, New Guinea, the Philippines, Sri Lanka, Thailand, Vietnam, Myanmar, Australia, Tonga and Samoa. In Australia it occurs from Cooktown to the Jardine River on Cape York Peninsula. It grows in seasonally inundated and other moist areas, in sunny areas near swamps, seepages, and small streams. In Australia it flowers from September to April.
