We think of a carrot as a sort of straight orange root vegetable, but that's just one such carrot.
As of July 2009, European farmers will be able to market wonky carrots [1] in the European marketplace.
Here's a bit (actually a lot) of history of the carrot at The Carrot Museum [2] for everything you always wanted to know (and more) about carrots.
If you've read Michael Pollan's Botany of Desire [3] you probably know that apples hail from Kazakhstan [4]. Did you know that carrots come from Afghanistan?
If you're in Europe in the coming months, look for such odd shapes as this one (smart Europeans - no longer a "family holdback" this - waste not want not):
Oh yes, and carrots are not just orange either. Anyone in Cleveland growing purple carrots?
