Glass Gem Corn (Zea mays) is a triple use corn. Grow to maturity for popcorn or flour, or let dry on the stalks for stunningly beautiful decoratives. A brilliant open-pollinated variety from Oklahoma, created by successive and stabilized crosses of several Native American (Osage and Pawnee) varieties. The result is appropriately named for its translucent rainbow of colors. Stalks grow 6' to 8' and produce an abundance of 7" to 8" ears. Corn is easily grown in blocks, especially in home gardens where they will get the attention they need to be successful. This is a very nice popping corn! 100 Days. 50 Seeds.
