You need to visit Wakeena Nature Preserve down here in the heart of the Hocking Hills. It is one of the last areas still being staffed by the Ohio Historical Society. The plant diversity is incredible. If you're a fern lover, there are nearly 30 species here.
Both the orange and yellow Jewelweed (Touch-Me-Not) are common here.
While maybe not as showy as others, the Arrow-leaved Tear-thumb is a common wetland inhabitant. Upon examination of the stem, you'll see where the name comes from.
