Pink Lady’s Slippers Flowering

pink lady's slipper2   223Pink Lady’s Slippers (Cypripedium acaule), also known as Moccasin Flowers, differ from Yellow and Showy Lady’s Slippers in two fairly obvious ways. One is that the stalk the single flower is borne on bears no leaves. In addition, the pouch, or labellum, has a vertical slit running the length of it, rather than an oval opening on the top. Bumblebees are the only insect strong enough to push their way through this slit and are their main pollinators. In New England, almost 25% of the Pink Lady’s Slipper population have white flowers (see insert).

  1. Where I walk each day there are hundreds of pink lady slipper flowers. Yesterday I saw this white flower that I have not seen before, I will send a clip.

    If Bumblebees are the main pollinators, who are the Vermont pollinators?

    • Oh, Clyde. It’s too early in the day for my brain to think of a clever reply! 🙂

    In all my years walking the woods, I’ve never seen a white lady slipper…is the 25% concentrated in a particular part of New England?

    • That I don’t know, Doreen. I agree, at least in Vermont, it seems much more like 5%, if that!

      I live in the western mountains of Maine and in our white pine tree farm, we have lots of whites and no pinks.
