Cypripedium x alaskanum, which is a natural cross of Cypripedium guttatum and Cypripedium yatabeanum. Just got this one this spring and didn't expect it to bloom and it may be the only time I see it bloom as it requires extended period of cold. The blooms are very small only about an inch in any direction. It is covered with a quite a bit of mud from heavy downpours we have had.
My Cyp. Michael did not bloom this year, I think slugs may have gotten the only bloom that may have formed.
