Corn Glass Gem
New for 2022


Glass Gem

Popcorn Seeds

110-120 days

As the result of many years of hybrid crosses between several varieties of native American popcorn and flint corn, Glass Gem produces extraordinary 3-8 in. ears of translucent, glass-like kernels in many rich, jewel-toned colors. Upright plants range in size from 6 to 9 ft. tall. Pop Glass Gem kernels into delicious popcorn, grind them into a colorful cornmeal, or dry the ears to use as decoration for spectacular seasonal displays.

Popcorn seeds cannot ship to Canada.
50 seeds - $3.49

Growing Glass Gem Popcorn Seeds

Bee introduces how to plant

Direct sow 5-6 seeds per foot, about 1-2 in. deep in rows (a minimum of 4 rows will ensure pollination) 3 ft. apart. Thin to 12 in. apart. Kept at 70-90°F., germination is in 7-14 days. If birds are a problem, sow in cell packs and transplant into the garden 1 ft. apart. Plant in spring to early summer, after all danger of frost, and when the ground has warmed.
