Just heard that local horticultural people have concurred that the plant is Lesser Celandine. Thanks for the help!
One of the people in our group looked at marsh marigold in a local garden and decided it is also a much bigger plant than the one we have. Thanks.
Thanks looked at photos from sources and will compare them to plant - seems close.
Need help in identifying this plant. Local garden center can not identify plant. The plant in the photo grows like a ground cover in a woodland...
