Nodding Ladies’ Tresses (Spiranthes cernua) is a beautiful terrestrial orchid native to the Eastern United States and Canada in USDA planting zones 5a to 9b. In Greek, Spiranthes is derived from the Greek words speria (coiled) and anthos (flower), and the species name cernua is Greek for cernuus, referring to the drooping flowers. The Greek or Latin derivatives of scientific names often describe specific characteristics of a plant.

The small, slightly fragrant white flowers are arranged in a spiral around the 9- to 18-inch spikes and magically appear in the late summer to early fall after the basal leaves have disappeared. As the flowers don’t have nectar spurs, they are pollinated by bees, and the small seeds are wind-borne. The older, lower flowers on the spikes have more nectar, so bees usually start at the base of the flower spike. The spiraling growth habit of the flower spike is caused by uneven cell growth.
The upright foliage has 3 to 4 basal lance-shaped leaves, which wither right before the flower spikes emerge. The simple leaves have entire margins (smooth with no wave or pointed edges) and are 2½ to 11 inches long.

It grows in anthropogenic habitats (meaning disturbed) and in partial shade in meadows, the edge of forested areas, and wetlands. From late August to early September, I’m looking for these flowering in open grassy areas on my farm. Keep an eye out for these beautiful, delicate orchids.
