Growing Information
Growing Glass Gem Corn
‘Glass Gem’ is a stunning open-pollinated corn variety prized for its translucent, jewel-toned kernels in a dazzling mix of colors. Each ear develops its own unique pattern, creating a stained-glass effect that makes this variety as decorative as it is memorable. Tall, sturdy, productive plants yield an abundance of colorful ears that are sure to stand out in the garden and at harvest time.
Sow ‘Glass Gem’ directly in the garden about 1 inch deep. Space plants about 3 feet apart and grow in full sun. This heat-tolerant variety performs well through the summer growing season.
Ready to harvest in about 100 days, begin checking the ears as they approach maturity and harvest according to your intended use.
Colorful, versatile, and eye-catching, ‘Glass Gem’ is well suited for decorative use, popping, grinding into fresh flour, and fresh eating when harvested young.
