Under the shade of a large beech tree, you may find small, woodland orchids called crane-fly orchids. In the early spring, green leaves with purple undersides can be found on the forest floor. The leaves fall off as the stem grows to about a foot tall, and then the flowers bloom in small, yellowish-brown clusters. Moths in the Noctuidae family pollinate these flowers.
The orchid can be hard to spot among the leaves on the forest floor (Megan Ossmann/NOAA).
In the late spring and early summer, the orchid blooms into a flowering stem that is 15-20 inches tall (Courtesy of Laura Morriss/USDA).
