The purple spike flowers of Prairie Blazing Star are reaching peak bloom. That will help attract butterflies for the Butterfly Walk that will be held next week. The walk is free and open to the public. It starts at 10 AM at the PGT Visitor Center. We usually finish near noon. We are lucky to have Donna Brunet to lead the walk again. Please contact us if you would like to attend. Walking near the PGT visitor center this afternoon I photographed an Eastern Tiger Swallowtail feeding on the Prairie Blazing Star.
