On a walk in the Bowling Green, OH Wintergarden Park I photographed Wild Geranium (Geranium maculatum) going to see. It is easy to see why it is in the family with cranesbills and why in Europe it is sometimes called Wild Cranesbill. I was able to find a plant with a flower and a seed pod both for this photograph.
I also spotted a wildflower that looks like a super dandelion. I did not have any books with me, so when I got home it appears to be a Hawkweed (Hieracium), probably a Meadow Hawkweed (Hieracium caespitosum) but there are a LOT of varieties of Hawkweed. This one had basal leaves only, with the flower cluster atop a 12-24 inch hairy stem. The basal leaves were also hairy on both sides.
