Hedge Bindweed

Another bindweed today. I have a moth but haven't i.d.'d it yet.
This is the other, perhaps more familiar, bindweed: Hedge bindweed. Unlike Field bindweed this is not Convolvulus, it is Calystegia sepium. 
It's seeds can remain viable for up to thirty years, so enjoy the flowers but rip it out before the seed sets if you don't want to be overrun.
