I thought I'd try to start a series of threads regarding native orchids. Hope others will join in with their images.

This is the Pink Ladyslipper, Cypripedium acaule, which normally occurs (at least here in Michigan) in dry pine woods.

This is also a Pink Ladyslipper, but is a very rare occurrence - an 'albino' form. This plant continues to come up every year (that I have checked) so I'm not sure where it gets it's nutrients from (no chlorophyll).

Cypripedium calceolus, Yellow Ladyslipper

Cypripedium calceolus parviflorum, Small Yellow Ladyslipper. This one is restricted to wet cedar swamps and calcarious soils of Michigan's Upper Penninsula.
