The northern range limit of the species along the Atlantic Coast is uncertain; see notes on gene flow and apomixis under 14. Spiranthes cernua.
Spiranthes odorata, marsh lady's tresses[1] or common lady's tresses,[2] is a species of flowering plant in the orchid family, native to the southeastern United States, from Texas eastwards and northwards to Delaware.[1] It grows in moist, partially shaded environments with acidic or neutral soil.
An herbaceous perennial, this orchid grows up to 50 cm (20 in) tall and broad. The flowers are borne in dense vertical rows on sturdy green spikes, in a slightly twisted pattern (hence Spiranthes, "twisted flower"). This effect is due to uneven cell growth. The flowers, which appear in late summer and autumn, are white, hooded and fragrant (hence the specific epithet odorata).
This plant is pollinated by bumblebees, notably Bombus pensylvanicus, Bombus fervidus, Bombus impatiens, and Bombus nevadensis.[3]
In the UK, the cultivar ‘Chadd’s Ford’ has gained the Royal Horticultural Society’s Award of Garden Merit.[4][5] Requiring a fertile soil in partial shade, it is hardy down to −10 °C (14 °F), but in frosty areas needs a dry mulch during the winter months. Botanically it is not actually a Spiranthes odorata but a different species called Spiranthes bightensis.[6]

Spiranthes odorata, ou spiranthe odorante[1], est une espèce de plantes herbacées vivaces de la famille des Orchidaceae.
Plante herbacée vivace, cette orchidée pousse jusqu'à 50 cm de haut et de large. Les fleurs sont portées en rangées verticales denses sur des épis verts robustes, dans un motif légèrement tordu (d'où Spiranthes, « fleur tordue »). Cet effet est dû à une croissance cellulaire inégale. Les fleurs, qui apparaissent à la fin de l'été et à l'automne, sont blanches, cagoulées et parfumées (d'où l'épithète spécifique odorata ).
Cette plante est pollinisée par des bourdons, notamment Bombus pensylvanicus, Bombus fervidus, Bombus impatiens et Bombus nevadensis[2].
Espèce originaire du sud-est des États-Unis d'Amérique, son aire de répartition va du Texas à l'ouest jusqu'au Delaware au nord[3].
Elle pousse dans des environnements humides et partiellement ombragés avec un sol acide ou neutre.
Au Royaume-Uni, le cultivar 'Chadd's Ford' a remporté le prix du mérite horticole de la Royal Horticultural Society[4],[5].
Nécessitant un sol fertile à mi-ombre, elle est rustique jusqu'à -10 °C, mais dans les zones à gel plus intense, il faut un paillis sec pendant les mois d'hiver.
