Both! Mainly ivy-leafed toadflax in the trough, which tends to blanket things; I also have some purple toadflax elsewhere, which I am tolerating because it is pretty (I even rescued it when I was emptying out the pot in which it originally appeared) but am attempting to keep an eye on before it sets seed. It doesn't help that I also have flax, phlox and alyssum, all four of which look very similar until they flower...
