Geoff, you're determined to get asters or penstemons into my garden aren't you? Aster would be more likely than penstemon, as I seem to remember planting one which never came up, but I thought it was in a different place. (By the way, the others turned out to be sweet william).
Smudge, you are right about the first one, I think it is the rather cutely named mouse-eared hawkweed, which is described as "a serious weed" (probably because it reads a lot), although it does have medicinal properties apparently.
