Greater Bindweed, pernicious perfection

Greater Bindweed

I know I shouldn't, I know I will ultimately pay the price for letting a little grow, but I love this devastating weed.  It's said that the roots can go down 15 feet into the ground.  Only a little chip of root needs to survive for it to start growing all over again.  It will develop into smothering ground cover and a choking climber if left alone.

I let a little grow under and up into the hedge in the wilder part of the garden.
