NPR has a beautiful interactive graphic on farm foods around the country. It looks like they began compiling this earlier this summer as part of Morning Edition series. It covers a random assortment, but includes some less familiar items like fiddleheads, nopalitos and daikon. If you don't know what those are, you should check this out. Whether you're looking for a good little story (with audio), some quick facts and tips on how to buy these fruits or vegetables, or recipes, it's all here.
