Thank you for the question. The plant is Virginia waterleaf, a Minnesota native perennial and bee friendly flower. Some have silvery spots on the leaves that look kind of like water, hence the name, but others have solid green leaves. Beauty is in the eye of the beholder and many people think they are lovely.

The easiest way to control them if you don't like them is to pull them out. If you need more advice on removing them, please submit another question.
Thank you for contacting Extension.
