In Florida this native flower is known as the bellflower. It’s “real” name is Campanula, which actually means little bell in Latin.
Surfing the net (old 90s term), I found many people calling this plant a weed. I found a great quote by Ralph Waldo Emerson that sums up my feelings about this. A weed is “a plant whose virtues have yet to be discovered.” Couldn’t have said it better myself. That’s why he’s famous and I’m not.
