Facts About this Plant:

Ranunculus pensylvanicus, or Pennsylvania Buttercup, is a native to the northern tier of the United States, as well as the southwest. It is an annual, or short-lived perennial, of moist areas, like ditches, wet fields and lawns, swales, fens and shorelines. It blooms in late spring and summer, with medium sized yellow flowers.

There are many Ranunculus species, but this species can be distinguished by its smaller flowers, the long length of its remaining seed pod, its annual/short-lived nature and its moderately hairy stems. The elongated seed pod is also common to Ranunculus sceleratus, which shares an annual nature and a preference for moist habitats, but it has a glossiness to its leaves, and its seeds are almost completely circular, with maybe a small nub on them, while Ranunculus pensylvanicus has hairy leaves and its seeds have a distinct spike on the end.
