Spiranthes porrifolia is a species of orchid known by the common names creamy lady's tresses[1] and western ladies' tresses. It is native to the western United States from Washington and Idaho to southern California.[2] It can be found in moist habitats, such as mountain meadows, swamps, fens, and riverbanks.[2] It is a perennial herb growing from a tuberous root system, reaching a maximum height around 60 cm (24 in).[2] The leaves are mainly located around the base of the erect stem. They are linear or lance-shaped, or sometimes nearly oval. The top of the stem is occupied by the inflorescence, a dense spiral of many flowers. Each flower is somewhat tubular, with an upper and lower lip, and cream to yellowish in color.[2]
