Glass Gem

Gorgeous translucent, jewel-colored ears, each one unique. A stunning variety selected over many years by Carl Barnes, a part-Cherokee farmer and breeder from Oklahoma. Selected from crossing several traditional corn varieties and saving seed from the vivid, translucent kernels. Gifted to NS/S by Bill McDorman who acquired the seed from Greg Schoen, one of Carl’s students. To read the story behind this magnificent corn, check out this Native Seeds Blog post .
