It grows into vines a few feet long, not very tangly, that run along the ground and don’t seem to climb. It seems to grow in large numbers of smaller vines that don’t seem to be connected in the roots.

Its completely blanketing my garden, choking out even other weeds, trying to expand into my lawn, and growing almost as fast as I weed it.

I’m wondering what it is, and/or if there are any particularly good ways of dealing with it. I’ve been tilling the ground, flipping over the soil (down to roughly a foot) and putting a layer of mulch over it, but Im still having stuff grow back.

Edit: solved: its periwinkle.
