IT IS A BEAUTIFUL TIME along the roadsides of Minnesota. Summer is gradually transitioning into autumn, and the season of gold into purple. Here Giant Goldenrod frames the deep purple of Joe Pye Weed. Bumblebees love Goldenrod, while Joe Pye Weed, named for a Native American sachem named Joseph Shauquethqueat (Joe Pye) is a favorite of butterflies. Gorgeous.
