Discussion

Variety hirsuticaule is encountered mainly in mucky soils in upland glacial deposits of southern Ontario, in the eastern and western Lake Superior areas at the northern limit of the deciduous forest, west to southeastern Manitoba, northern Illinois and Michigan. Plants tend to bloom slightly earlier than do those of other varieties in the area and often the stems are stouter.
