Would it be the Celandine Poppy (Stylophorum diphyllum)?
Celandine Poppy Stylophorum diphyllum
It looks to me to be a Wood Poppy. With the help of Amanda’s Gardens from Springwater, NY, I’ve had much help in trying to establish plants that are Native to our area and this is one of them.
I would say it is Stylophorum diphyllum aka Wood Poppy or Celandine Poppy in the Papaveraceae family. We had these in our yard when I was growing up, in Michigan.
ranunculus repens or meadow buttercup
Oh wait, was I ever wrong. I was dealing w/pics the size of a postage stamp. Now that I’ve posted, I see a much larger image (isn’t that ALWAYS the case when posting on a public forum?? My bad).
Looks like Ranunculus bulbosus, bulbous buttercup.
looks like Stylophorum diphyllum Woodland Poppy
Buttercup (Ranunculus repens).
As so many of you noted, this is Celandine poppy (Stylophorum diphyllum), also known as Wood poppy. The first time I saw this plant was at a local botanical garden. Now, I visit there every spring to enjoy the bright yellow flowers.
