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.

Would love to rate but.,,

I unfortunately never received the glass gem corn seeds. I guess the parcel got lost in the post…

The site was easy, the delivery was perfect, but I can't review the seeds... it's just not the season to plant them and to find out what I actually think about the seeds. The order was easy and quick.


Planted in late March, harvested in early July (San Antonio, TX; Zone 8b). The plants grew well and seemed more drought-tolerant than other corn I've grown. The ears were very colorful and filled in nicely. I processed them into masa and made tamales. Definitely happy with the result and will plant again.
