Arrived in my gardens a few years ago and new plants arrive each year. Flower has sweet aroma and bees are attracted as well as the butterfly....
Wow...that is a "perfect" match. Thank you so much. Well, I guess a weed is anything that grows in the wrong place...and this vine is taking over.
Somewhat thorny with pointed shovel-like leaves. In the fall produces purple like berries. Have no clue...just arrived in garden and is taking over.
