Corn like bananas have been domesticated so long they don't grow naturally, and need sowing. Bananas are so domesticated they're extinct in the wild and have to be cloned. Have been for like 2000 years. Matter of fact, the entire genus is going the way of the dodo due to virulent mycosis, same as pollenating bees and amphibians.
(Wanna see a world-wide clusterfvck, wait until bananas disappear.)

Someone mentioned Monsanto seeds.

Stay away from those poison pills.
