I am new to the UK from the US and haved moved into a wonderful cottage with a rather extensive but overgrown garden. There is something(I can only assume that it is a weed) that has taken over virtually every inch of the beds, but after scouring the internet, I have been unable to identify it. Can anyone help? I would also appreciate any advice on eradicating it. I would like to clear my beds and plant, but would hate for it to take over again, as it looks like it is quite aggressive. Any help would be great!
