This is a northern species. Many specimens are from open, sandy woods and I found a very sandy, fallow field of about five acres that was covered with old-field balsam and this species. This species was rare and found in the moister situations. The plants were much taller and, in most instances, with several branches from near the base that were almost as large as the central stem.
