Glass Gem is a unique strain of corn with kernels that look like pieces of rainbow-colored glass. Source
Carl Barnes, an Oklahoma farmer, started growing older corn varieties to connect with his Cherokee heritage.
He isolated ancestral strains Native American tribes lost in the 1800s when they were relocated to Oklahoma.
Soon he began exchanging ancient corn seed with growers from all over the country, while simultaneously saving and replanting seeds from the most colorful cobs.
This eventually resulted in rainbow-colored corn.
When the rainbow corn mixed with the traditional varieties it created new strains, displaying more vibrant colors and patterns over time.
Glass Gem is a flint corn, so it isn’t really eaten off the cob. It’s usually ground into cornmeal and used in tortillas or grits, but it can also be used to make popcorn.
If you love corn and rainbows, seeds can be purchased online for about $7.95.
