European Marsh Thistle is native throughout much of Europe. It is an herbaceous, facultative biennial that favors moist and seasonally flooded sites. It grows best in sun but can tolerate shade also. In North America, European Marsh Thistle is found New England, some Great Lakes States, including NE Wisconsin and the upper peninsula of Michigan, as well as Ontario and British Columbia. There are no known occurrences of it in Minnesota.
Review Entity | Outcome
NWAC Listing Subcommittee: Suggest regulation on the Prohibited-Eradicate list.
-Not known to be in MN at this time, but reputable sources have claimed to see it right across the border in NW WI.
-Some discussion about how this compares with other biennial thistles.
-Thoughts to list this species now to get the word out on it and re-evaluate in 3 years.
NWAC Full-group: No Regulation at this time.
