No, Glass Gem Corn is a flint corn variety rather than a sweet corn. Its kernels have a hard outer layer, making it unpalatable for fresh, boiled, or steamed eating. It is best used for decorative displays, popped as popcorn, or ground into dry cornmeal and flour.

Allow the ears to fully mature and dry directly on the stalk. Harvest when the husks turn brown, dry, and papery. If rainy weather threatens your crop at the end of the season, cut the cobs in their husks and bring them indoors to finish drying in a cool, well-ventilated area.

Yes. Corn is pollinated by wind, so planting in blocks of shorter, parallel rows (such as 4 rows of 4 plants) leads to significantly better pollination and fully filled-out cobs than planting in one long single row.

While the unpopped kernels feature striking rainbow colors, the starchy interior of the kernel is white. When heated, the kernel turns inside out, resulting in small white or off-white pieces of popcorn with dark, colorful tiny hulls attached.
