Discussion | The six varieties and forms of Silene antirrhina noted above were named on the basis of stature and flower color, but none appear to be worthy of recognition. The species is very plastic, being greatly affected by moisture, exposure, and nutrients. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
