This photo shows a wood poppy, Stylophorum diphyllum, which I found growing in High School Park in Elkins Park, PA, in Cheltenham Township. This park is filled with spring wildflowers, including mostly native ones.

An interesting educational opportunity for plant identification, though, also lies in this park, as it contains both this native plant, and the easily-confused greater celandine, a similar-looking plant also in the poppy family, introduced from Europe and invasive in this area.
