Cypripedium acaule, or Pink Lady's Slipper, grows in the Midwest, as well as the Appalachian and New England areas of the US; it is perennial orchid with beautiful pink flowers. It grows in open pine and oak woods, or sometimes even in bogs. It can be seen growing in moist or dry situations, but it is always in areas where the soil is very, very acidic. It is also said to require a microorganism in the soil to survive - this is typical of most orchid species, as they usually need this for their seeds to germinate, but most of them shed this need once the plants are mature; this is said to still require it.

There is no other Cypripedium species like Cypripedium acaule; not only does it have solid pink flowers, unlike the others in the genus, but it also has a single stem, with a single flower on it, with only two leaves that remain at the base of the plant, the ground (this is known as "basal," meaning at the base). All other species in the genus have stalks with many leaves, and often multiple flowers
