Description

Spiranthes laciniata plants are a tall species of Spiranthes reaching a height of 20–95 cm, with up to 5 basal leaves persisting through anthesis. The flowers are white to cream-white and arranged in a spiral around the stem. The lip is usually yellow in the center. Bloom time is from May to (at its northern range) September.[1][2][3]

Distribution and habitat

Spiranthes laciniata is native to the southeastern coastal plains, from Texas in the south all the way to New Jersey in the north.[3]

It is a wetland plant and grows in swamps and marshes, sometimes even in standing water.[3]

Taxonomy

The Spiranthes laciniata name was first published by Oakes Ames in 1905, after John Kunkel Small had described the plants in 1903 as Gyrostachys laciniata.[4]
