Can anyone tell me what this very quick growing plant is? It first grew last summer in my veg patch and I let it flower to see what it would do, but cut it down at ground level before it could disperse its seeds. It's come up again this year now with three main stems and is growing about 3 inches per day.
First two photos are last years version and last one is this years. I'd like to find out what it is before I dig it up and exterminate it!
