farmcat, the year before last we  grew Bloody Butcher Corn though I don't know how true to name it is because the seed was saved seed,  given to us from a farmer,  via a friend.  It is a very tall and sturdy corn and produced well though we only got one large dark red ear per plant.    It actually grew between 9 and 10 feet tall.   It made good cornbread though the color was a little odd,  slightly greyish with tiny flecks of dark red.   This past summer we planted a mixture of field corn, both yellow and white,  that we have saved over the years but included some of the red.   It was easy to tell which were the bloody Butcher plants as they grew about a couple of feet taller than the rest.  It was fun shucking the corn out after it dried as the color of the kernels is a suprise,  there was everything from white through yellow, some red and even a few greyish blue kernels (from an ear of Indian Corn thrown into the mix several years ago).   I find cornbread made from home crown corn a little denser than cornbread made from the self raising meal most people use.  I don't know if this is because everything is left in the home grown corn but we really do prefer the flavor.

We purchase from a local organic farmer not far from our home. If this isn't an option for you and you don't want to do mail order, have you ever gone to localharvest.com?
