Glass Gem

  • ZP103
  • 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.

    • The kernels may be ground into cornmeal or popped.
    • Size of ears range from 3-8 inches. 
    • Height of plants depend upon water, but can reach up to 9 feet, typically 6 feet. 
    • Glass Gem can be harvested approx. 110-120 days after planting when the husks are dry and brown for the most intense and translucent colors. 
    • Packet size 7g/approx. 50 seeds 

    • Seed Saver Size includes approx 35g/250 seeds plus information on corn pollination and seed saving.

Amazing corn seeds & company to purchase from. I couldn't have asked for anything more at any point of the Glass Gem Corn process. I Love supporting American farmers Made in USA! I love the history & supporting Indigenous People (or Native American)...sorry I don't know what I'm supposed to use now days because there are different answers. Thanks again! I literally can't wait to pop my first batch of popcorn! My family & co-workers are also very excited.
