Please Help ID This? Fast growing, a weed?

We have no idea if we planted it or if it's a weed. It appeared and grew fast as lightening. Hasn't flowered yet.

Can anyone help with the ID of this thing?

 

I have those here too. And while I don't know what it is, I DO know it never blooms. I call it a weed and pull it out!

 

I would think it is a weed also. It resembles something here too.

 

My hubby pulled it out about an hour ago. He said the root system was gigantic.

 

how come plants with beautiful long lasting fragrant flowers don't grow that fast and tall????

 

cherylad, I am sure there s a very good answer on this somewhere but it escapes me at the moment.
