I wish I knew more about this plant. My wife and i both believe that people used to put the flowers in drawers with clothes, to make them more fragrant. The plant was growing in a sunny area, along US 123 in Pickens County. It was about 3/4 meter/yard tall, and the flower, or flowering head, was about 2 inches/6 cm across. This photo represents the actual reddish brown color pretty well. Any alternate color name suggestions would be appreciated.
Thanks to gravitywave from the ID Please group for the identification. This is Calycanthus floridus. As the photo's new title suggests, it has a lot of common names, including strawberry shrub.
