About Spiranthes porrifolia Lindl.
Spiranthes porrifolia Lindl. is an orchid species, commonly known as creamy lady's tresses and western ladies' tresses. This species is native to the western United States, where its range extends from Washington and Idaho down to southern California. It grows in a variety of moist habitats, including mountain meadows, swamps, fens, and riverbanks. It is a perennial herb that grows from a tuberous root system, and reaches a maximum height of around 60 cm (24 inches). Most of its leaves grow around the base of its upright stem; leaves can be linear, lance-shaped, or sometimes nearly oval. The upper part of the stem holds an inflorescence, which forms a dense spiral of many individual flowers. Each flower is somewhat tubular, with distinct upper and lower lips, and ranges in color from cream to yellowish. Its specific epithet porrifolia is Latin for "leek-leaved".
