These weeds (for lack of a better word) growing on the rear of our property, in an area untouched by me, are very attractive to the butterflies. I probably wouldn't have even noticed them had I not been looking down in order to avoid a snake hidden in the tall grass. I am sorry to say that I don't know their names because they are certainly worthy of being known. They are simple little flowers that were attracting a variety of butterflies in all sizes. They darted from flower to flower, happily sipping nectar on a sunny autumn afternoon.
This looks like a morning glory but it wasn't growing on a vine. Perhaps it is a wild petunia.
This one was the butterflies favorite!
I believe it was Emerson who said, "A weed is a plant whose virtues have not been discovered."
