Personally, I question the origin of a lot beans. Anybody can claim they're from anywhere, or simply rename it as was frequently done by heirloom seed catalogues for many vegetables. Giving something a new name and story is a great selling option, realtive to the cultural interests of any given time period and also having 'new' varieties. I just read, conicidentally, last night about a bean called 'Seneca Bird Egg' which turns out to be historical fiction. It's apparently from Chile, and somwhere along the way aquired this fictitous name and association. Chile only donated this bean to the USDA in 1988. So I guess it doesn't take very long for things to get mixed up.
