Budleja Davidii

 

Buddleja I would imagine. Not a great place for it so it's your call!

 

You beat me Zig. Grr!

 

Think it was a tie Chris

 

They transplant ok, I usually pot up self seeded ones.

 

FC, first of all I'll own up to not being a fan so might be a bit biased . They are quite deep rooted, grow fast and can be very tall and put on a lot of girth. I have one that is about 12 ft tall and I've hacked it down often and it just zooms back.
I see that it is right next to your house. Personally, I'd get that out immediately before it takes hold as they are very stubborn to get rid of once they take hold. The roots are a bit aggressive and you don't want that close to your foundations/walls. Also, some varieties are quite handsome while others are quite weedy and feeble looking and wishwashy flowers.
To sum up=get rid.
My tuppence for what it's worth.

Good luck with that.

 

If you don't want in the border, you can always put it in a large planter. I have a Pink Delight in a planter Smells lovely when in bloom and loved by butterflies (hence why they are known as the butterfly bush).

They are tough as old boots and very easily propagated (I took a cutting from one of mine a couple of months ago, which I just dipped in rooting hormone and then shoved in the pot next to the parent plant). It's doing very well and once it's large enough will be potted up

So I would say - take it up and put in a large planter.
