Common Ladies' Tresses

Common Ladies' Tresses (<em>Spiranthes cernua</em>) is a terrestrial orchid in the family Orchidaceae, native to North America and parts of Europe. Its range includes Belgium, Canada, and the United States, where it typically grows in grasslands, wetlands, forests, and cultivated landscapes. The species is characterized by a spiral arrangement of small white flowers along a slender stem, giving rise to the common name. It typically favors moist, open habitats including wet meadows, stream banks, bogs, and the margins of ponds, though it also occurs in drier grasslands and open woodlands. As an orchid, it depends on mycorrhizal fungi for germination and early establishment. Its conservation status has not been formally evaluated by the IUCN. Common Ladies' Tresses is considered a late-season bloomer in temperate North America and is valued as an indicator of high-quality natural habitats where it persists. Biological traits of this species remain poorly documented in the scientific literature.
