Arundina graminifolia is a species of orchid from the genus Arundina.
Arundina graminifolia is a terrestrial multiperennial orchid with reedy stems, forming large clumps growing to a height of 70 cm to 2 m.
This orchid blooms in summer and autumn, showing rather open clusters of showy terminal flowers, ten at the most. They bloom in succession on the terminal racemes, which are 7 to 16 cm long. These flowers, 5 – 8 cm in diameter, are a rosy lilac and white disk with a purple lip. The bracts are wide triangular and surround the main stalk of the flower cluster. The occasional fertilized seed pods contain minute powdery seeds, and small plants often develop near the cane ends after flowering, and likely aid in propagation if allowed to reach the soil.
With only 200 of the plant to be recorded growing naturally in Singapore, the species is close to extinction there, largely because of destruction of its natural habitat, namely the rainforests and mangrove forests. The remaining plants, commonly called Tapah weeds, can be found in the secondary forests or at the forest fringes. It is however very common in road cuts and other disturbed areas in full sun in Sarawak, East Malaysia, where it often is the most common flowering plant to be seen along the roadsides.
The plaited linear leaves are oblong lanceolate, with a length of 9 to 19 cm and a width of 0.8 to 1.5 cm. The apex is acuminate. There are amplexicaul (clasping the stem) sheaths.
This tropical Asiatic genus extends from India, Nepal, Thailand, Malaysia, Singapore, South China to Indonesia and across the Pacific Islands at elevations of 0 to 1000 meters. It was introduced to Puerto Rico, Costa Rica , Guatemala and Panama.
Plants grows in intermediate to warm temperatures with shade. When potting Arundina plants, the pseudobulbs must be half buried into the potting media. Plants can be potted in 40% soil, 40% dry bark and 20% perlite or another humus rich soil mixture. Plants should be watered regularly.
