Know before you buy
No, Glass Gem is a flint corn variety, not a sweet corn. It is best used for grinding into cornmeal, popping, or as a decorative display rather than eating fresh off the cob.
Corn is wind-pollinated, and planting in blocks—rather than a single long row—ensures that pollen from the tassels reaches the silks on the ears more effectively. This results in better kernel development and fuller ears.
Glass Gem Corn is a vigorous grower that typically reaches between 7 and 9 feet in height. Make sure to choose a spot in your garden that can accommodate this height without shading out smaller plants.
Yes, these are organic, heirloom seeds. As an heirloom variety, they have been preserved for their unique traits and are not genetically modified.
This corn requires full sun exposure to thrive and produce its vibrant colors. It needs a consistent supply of water, ideally about 1 inch per week, to support its rapid growth and ear development.
Under proper soil conditions, you can expect germination to occur within 7 to 14 days after sowing. Ensure the soil is warm and the seeds are planted 1 inch deep for the best results.
