The Oak Leaf Trail, in Franklin, Wi., south of Drexel Ave. The trail goes north as well and is used for biking and running.
The Prairie Trillium isn't a common as the white Trillium here.
While exploring along the Oak Leaf Trail, part of the parks system here in Franklin, I found a great spot with a number of these red, Prairie Trilliums. The deep red of the flower amongst all the green was quite the sight.
