In case you don't find a source here I found this https://www.etsy.com/ca/listing/49068410/heirloom-seeds-vegetable-seeds-blue

I only have a sample and haven't grown them out yet so can't help you right now, sorry.

Hmmm... I've seen them offered commercially, but can't find a source at the moment. It is a pretty popular bean in the seed saving community, though, and quite a few people grow it. Eight people currently offer Blue Shackamaxon in the Seed Savers Exchange. Also, if you use the Gardenweb 'search' function, you will find several members here who grow it... contacting some of them might be your best bet.

I've bought bean seed from here and have had good results with them. I see Blue Shackamaxon on their list under dry pole.

Thanks for all the information. I will check these out.
