Glass Gem


Zea mays.  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.  From our Seed Bank Collection.

Glass Gem

Growing like crazy, but no ears of glass gem yet. Here in White Rock, NM at 6300 feet. Looks happy!

Very Pretty Glass Gem Seeds!

Haven't planted them yet, but they're so nice looking. Package was well packed and came FAST! I would buy from this seller again.

Growing well. All the seeds in the packet but one sprouted. Anxious to see the ears and their colors.

sample not as advertised

i feel that product received, not crop, should be as advertised. of course it cannot be known at this time if the crop appears as shown. fruition seeds is a bit better despite no actual pink, just as everyone advertises pink and sends purple at best. pink is purple to sapiens evidently: to them those colors are synonyms and useless tautology.

22 out of 28 seeds planted outside germinated and are coming along great!
