I should be interested to know whether you succeed in getting this plant completely out. Mine (which is not gold) seems to be a prolific source of root suckers which might escape your attentions. Maybe your new shed would look good festooned in golden hops!
Wise words Dick, suspect I've not seen the last of it yet!
Did you find a home for this? Any use for a bit of guerilla gardening somewhere?
Just to say, to any fool wondering about planting this in their tiny Harringay garden, DON'T! It took hours to dig out - roots as thick as my arm. Killed it in the process, sorry those who expressed an interest in it (but you have had a narrow escape).
