Hello all! This plant has taken over almost half of my already small backyard. There was a VERY large one growing up behind my fence last Fall, and this Spring, its babies popped up EVERYWHERE and overtook everything. I cut the large parent tree down. There is nothing around my place that looks anything like it, and I have never seen it before this past fall. It grows very rapidly, has a tree-like stem, and grows VERY tall (the mama tree thing was probably over 10 ft tall by the time I cut it down).

Can anyone tell me what it is? I need to get rid of it soon, as I am planning to list my condo for sale soon.
