This multi-colored corn is real and there's a fantastic story behind it

Glass Gem corn, a unique variety of rainbow-colored corn, became an Internet sensation in 2012 when a photo of the sparkling cob was posted to Facebook.

Shortly after, the company that sells the rare seeds, Native Seeds/SEARCH, began ramping up production to meet the high demand. The Arizona-based company still sells Glass Gem seeds on its website.

Meanwhile, a Facebook page devoted to Glass Gem allows growers to share pictures of the vibrant corn variety.

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.
