I have some Oaxacan green dent corn from last year's garden that I could send your way if I can figure out how to ship it (never shipped anything internationally before). It's a dry corn good for cornmeal and flour, and it's emerald green, which is kind of neat. I'm going to grow some Isleta blue flint corn this year as well, which is supposed to be one of the best flour corns. It also has 12 foot (4m) tall stalks, which can be a useful building material or
compost crop. It won't be ready until the fall though, and the Oaxacan is ready now.
