The photo is the plant Lesser celandine (Ranunculus ficaria). It is a very invasive plant that is often found in floodplain forests. In the northern section of the Rocky River Valley this invasive is very abundant. One of the problems is that it spreads in several ways including root tubers, leaf cuttings and seeds. It is very difficult to eradicate once it is established often choking out native spring wildflowers.
Thanks for the question!
