Thanks for the question.

I believe that this might be Mulberry weed (Fatoua villosa). Consistent with your picture, it has a somewhat fibrous root system that is white to tan in color. In both pictures, the plant appears to be growing up through some type of deck or walkway. This is also consistent with Mulberry weed as its height can exceed three feet. It is an annual plant that releases an enormous number of seeds, often propelling them several feet away from the plant itself. It is quite common in Minnesota and is considered invasive. It may be best for you to try and get rid of it. Its flower clusters are purple when young and fading to dark brown with age. To prevent the release of seeds, which now could occur at any time, remove the flower clusters as quickly as possible once they are visible.

Do a little experiment. Cut a few stems of the plant. If a whitish liquid emerges from the cut stem ends, this is consistent with the plant being Mulberry weed.

It is best controlled by applying pre-emergent herbicides in early spring (late to mid-March).

Good luck with dealing with this plant. It can quickly spread if left to its own devices. Please get back to us with any questions.
