Vanda coerulescens aka Periwinkle Pinwheel

Vanda coerulescens, also known as sky-blue vanda or Vanda coerulea orchid, is a small to medium-sized, evergreen, tropical orchid species native to Assam and Arunachal Pradesh, India, the eastern Himalayas, southern Yunnan province in China, Myanmar, and Thailand. It is a monopodial epiphyte that grows from a central rhizome, with new growth emerging from the tip. The plant has alternate leaf sheaths carrying strap-shaped, green or dark green leathery leaves, which gradually drop off as new leaves appear. The roots grow directly from the main stem. The inflorescences, ranging from 60 to 100cm long, emerge from the axils of leaf sheaths and the stem, bearing a large number of small, waxy, long-lasting flowers. The petals and sepals are narrow at the base and can be white, pale purple, or pink, while the small lip is usually darker in color. The Vanda coerulea orchid can reach a length of 75-150 cm and a width of 50 cm. Its stems are stout and carry distichous, ligulate, obliquely tridentate apically leaves that are coriaceous and conduplicate. The leaves, which are yellow-green and have deep grooves on the upper surface, grow unevenly and have a bulge on the underside. Leaves growing at the bottom of the plant fall after a few years.
