Weed or Flower?

This mound is growing on my neighbor side and some on my side of the fence. I'm new to the home. Not sure if I should cut it out. Its growing like a weed b/c its gotten so tall really fast. I think I've seen these branches on the sides of roads as well and they are at the same stage.

It is a weed and a very nasty one.

It is quite difficult to eradicate as it both seeds prolifically and can re-sprout from tiny root fragments. IMO this is a case where glyphosate herbicides are justified. I have had the best luck with cutting the hollow stems just below a node during or immediately following flowering and using a lab wash bottle to apply a strong (50%) solution of glyphosate into the hollow cavity. Ideally you want a non windy day with temps in the 70s or low 80s.
