I just bought a house and was trying to weed the yard when I found this viney flower in the back corner. They feel like little paper lanterns and smell so fragrant (if it isn't something else in the heap of bedding) and there was an open flower with a berry in the center. I couldn't find it in the dark but here's one photo. Does anyone know what kind of flower (or weed) this is? Is it good for a butterfly garden? Thank you!!
