Common NamesKalm's St. John's-wort
This species is native to the Great Lakes Region. There are a couple of old reports from our area- New York Co., NY and Middlesex Co., NJ- but no specimens have been seen; and these may represent a mis-identification of another Hypericum species or a label typo (geo-coding error).
