Cypripedium parviflorum var pubescens (calceolus) - Yellow Lady's Slipper
This is one of the prettiest and well-known native orchids. This is also one of the easiest orchids to grow in your garden, as opposed to the Pink Lady's Slipper, which is very difficult to grow. The Yellow Lady's Slipper prefers a rich soil with a pH of 5.5 to 6.0. It will reach a height of 1-2 Ft bearing a yellow slipper like flower on top in the Spring. This would make a great addition to your woodland garden.
