In the late summer and early fall, depending on where you live in the eastern U.S., this orchid blooms in wet meadows, bogs and fens. Nodding ladies tresses sprout through the chaotic growth of wild grasses, rushes and sedges with a spire of white blossoms no more than 12 inches tall. I have observed bumblebees sipping the nectar of this orchid making them efficient pollinators of this plant.
