Carolina Wild Petunia
Ruellia caroliensis /Acanthus Family
I like these pretty pale purple flowers. They may be found from late May throughout the early part of the summer. I photographed these flowers at the University of Tennessee Arboretum. I'm about 98% sure that I have the right species name on this plant, but that nagging 2% bugs me!
