On twitter today I saw a tweet about glass gem corn along with a beautiful photograph, which you can see here.
The tweet says: “Pre-colonization Glass Gem Corn, Indigenous to North America, regrown by a Cherokee farmer in Oklahoma. This particular corn is a mix of ancient Pawnee, Osage and Cherokee varieties.” Native Seeds Search has the full story here.
The corn is incredibly beautiful. It looks to me to be too beautiful to eat! But you can buy the seeds and grow it yourself.
