Glass Gem corn, a unique variety of rainbow-colored corn, became an Internet sensation in 2012 when a photo of the dazzling cob was posted to Facebook.
Since then, the Arizona-based company that sells the rare seed, Native Seeds/SEARCH, has been ramping up production to meet the high demand.
A Facebook page devoted to Glass Gem allows growers to share pictures of the vibrant corn variety. It has nearly 4,000 likes.
But the story behind Glass Gem is just as remarkable. It begins with one man, Carl Barnes, who set out to explore his Native American roots.
The history was largely retold by Barnes' protegee, Greg Schoen, in 2012, when the corn gained national attention. We've broken out the highlights.
