it's getting huge!! And I don't know what it is. At this point it is well over 4x as large as it was in this picture.


When you try to pull on a branch, it is very strange... It pulls apart in joints. Any ideas what it is?
If it grows, I can kill it.

I would say Hibiscus rosa-sinensis. But I don't know what cultivar.

Sad to say, it looks like Variegated Japanese Knotweed (Reynoutria japonica 'Variegata')
Scary invasive and noxious in Nebraska:

Yep. That's it. Which is why it spreads underground like crazy and pops up all over the flower garden. Next year I'll annihilate it for good... Roundup!
