Summary
Spiranthes odorata, commonly known as Marsh Lady’s Tresses, is a perennial herb native to wet meadows, marshes, and the edges of streams and ponds in the southeastern United States. It typically grows up to 50 cm (20 in) tall and broad, with a distinctive growth pattern featuring flowers borne in dense vertical rows on sturdy green spikes. The flowers are slightly twisted, which is reflected in the genus name Spiranthes, meaning "twisted flower." This unique spiraling effect is due to uneven cell growth. The white, hooded, and fragrant flowers appear in late summer and autumn, adding a delicate charm to the garden. Marsh Lady’s Tresses is pollinated by bumblebees, contributing to the local ecosystem.
This orchid is valued for its fragrant, showy flowers and its ability to thrive in moist, fertile conditions. It is often used in water gardens, bog gardens, and as a naturalizing plant in damp areas. While it is hardy down to −10 °C (14 °F), it requires protection in the form of a dry mulch during winter in frost-prone regions. The cultivar ‘Chadd’s Ford’ has received the Royal Horticultural Society’s Award of Garden Merit, indicating its exceptional performance in gardens. For successful cultivation, Marsh Lady’s Tresses prefers part shade and soils with slow or medium drainage, and it requires medium to high amounts of water to mimic its natural wetland habitat. Potential problems include root rot if drainage is insufficient and damage from slugs and snails.CC BY-SA 4.0
