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.
As the common name implies, the plant can be used as a source of blue dye although it is not as desirable ('lighter shade of blue') as the true indigo (Indigofera tinctoria). Both species are in the pea family. Another source of indigo dye is 'dyer's woad' (Isatis tinctoria), a mustard, which was grown in Europe before true indigo started to be imported from Asia. Both true indigo and dyer's woad were grown in colonial America. Dyer's woad is now a problem weed in parts of the west.
