This plant has linear bracts at the base of the compound umbel which identifies it as T. japonica rather than T. arvensis. T. arvensis is not officially listed as being present in MN (by any organisation/website I could find) but there are a number of observations here at iNat attributed to T. arvensis in MN so I felt the need to rule it out for this observation. I found at least three plants and one decent size stand at this location and all were confirmed to be T. japonica. It is listed as an invasive species for MN (and many other states).
