Weed or flower
Plant identification can be very time consuming and requires a lot of detective work. It is especially hard when we have little information to go on.
For instance, we could use closeups of leaves and stems. Especially, we could use information about the flowers (photos, timing, etc.)
What else do you know about the plant? Has it come up in previous years? Have you seen it nearby? Is the location sunny or shady? Wet or dry?
Since you have the plant in front of you, it is often easier for you to make the identification than for us to do it on the basis of three photos. Here are some useful identification websites:https://www.minnesotawildflowers.info/
