About
Spiranthes odorata, marsh lady's tresses or common lady's tresses, is a species of flowering plant in the orchid family, native to the southeastern United States, from Texas eastwards and northwards to Delaware. 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).
