What kind of plant is this?
There is this stalk-like plant growing in the flowerbed again. Last year I let on of them grow because it grew superfast, just to see how large it got, and it went to about 8feet tall and tilting over before I took it out. It doesn't have flowers or anything, just leaves and a stem. The leaves are long(about as long as my hand) and thin (less than 1 in.) with serrated edges. Anyone know what these are?
I live in Pennsylvania.
The leaves are the whole way down the stem, and a little bit furry on the underside. There's one vein going down the middle.
Thanks!
