Fringed Polygala

Fringed Polygala (Polygala paucifolia) looks a bit like a miniature orchid, but it is not — it is in the Milkwort family. The structure of its ¾-inch bright magenta-pink blossoms is well-suited for its bumblebee pollinators.  The bee lands on the pink fringe at the front of the flower and its weight triggers the white “keel” to drop down.  A slit at the keel’s top opens, exposing the reproductive parts of the flower.  Pollen from the stamens is rubbed onto the bee’s hairs while it probes deeply into the base of the flower for nectar, while pollen from a previously visited Fringed Polygala is scraped off onto the stigma, where it needs to be in order for fertilization to take place.
