Miguel, you are right about tanguticas
You warned me. 'Bill MacKenzie' is growing so wide and out of control that he has to go. I swear it goes off in twenty directions. Not up the tree where it is supposed to. Looks like it is going to eat my entire garden and it is only two. Looks really weedy, not attractive at all.
'Helios' is still a great well behaved vine for me at three or four, can't remember but this big one has to freaking go.
