Great looking plants! I'm always delighted when I find these plants out in the woods. There is one particular nameless hill/mountain in CT that has pink lady slippers growing all over it's top. None on the sides or on the ground surrounding it, only on the top. It's a nice surprise if you get there when they are all in bloom.
Thanks. There's a popular recreational spot near me in Medford that has C.aucale (Pink Lady Slipper) growing in profusion. In some areas, it's hard not to step on them. C.aucale is actually very common to abundant across New England and is the most likely Cypripedium you will run across. It's not the extreme rarity some people believe it is. It is just a very habitat specific plant growing almost exclusively in dense pine woods that support the particular symbiotic mycorrhizae the plants depend on for survival.
Spend your life doing weird things with strange people.
