Platanthera praeclara, known as the Western Prairie Fringed Orchid or the Great Plains White Fringed Orchid, is a rare and threatened species of orchid native to North America. It has been listed as a threatened species in the United States since 1989, and in 2008 was added to the IUCN Redlist. The plant arises from a fleshy tuber. It grows from 1.25 to 3 feet tall (38-85 cm). Each plant can have up to two dozen or more flowers arranged in a stalk. P. praeclara is distinguished from Platanthera leucophaea, the eastern prairie fringed orchid, by its slightly larger flowers, petal shape, and longer nectar spur. P. praeclara is a long-lived perennial. It emerges in May and blooms in June or in July further north. The flowers are fragrant at night and are pollinated by large sphinx moths. P. praeclara is a plant of the tallgrass prairie and requires direct sunlight for growth.
