We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Deptford pink (Dianthus armeria) I think. If so, the petals should be 'pinked', i.e. with ragged edges and the leaves narrow and opposite on the stem. It is a close relative of carnation and another great example of some of the beauty of the dreaded 'non-native' species.
It is almost certainly one of the dianthus family, but precisely Which one, since they hybridize quite happily, I wouldn't care to guess. (D. armeria x hyb. seems reasonable). The pinking of the petal can range from complete, making them look like cornflowers, to essentially non-existent. I have a 'wild' one that is the most impressive saturated fuschia colour, it has a similar growth pattern to the one in the picture. It pops up quite happily here and there. It isn't a native, but it isn't doing any harm either, so I enjoy it.
