Rainbow Corn Purple | Glass gem Corn Purple

Purple Glass Gem (Rainbow) Corn is a breathtaking heirloom variety whose cobs sparkle with translucent, jewel-like kernels in rich purples and iridescent shades — like a handful of gemstones. As beautiful as it is edible, the kernels can be popped, ground into flour or dried for stunning ornamental display. Sow seeds in full sun in fertile, well-draining soil in blocks for good pollination, water regularly, and harvest in about 90–110 days. A magical, showstopping corn that’s a joy to grow and share — perfect for home gardens and curious growers.
