Glass corn on the cob, also known as Glass Gem corn, is a visually stunning variety of flint corn that captivates with its vibrant, rainbow-colored kernels. This unique corn is not typically eaten fresh off the cob like sweet corn. Instead, it serves ornamental purposes and can be used for making popcorn or grinding into cornmeal.

Glass Gem corn is left on the plants to dry naturally, allowing the kernels to harden and develop their characteristic glassy appearance. As the corn dries, the kernels lose some of their initial vibrancy but retain their multi-colored beauty. This drying process is crucial for preserving the corn for decorative use or preparing it for culinary applications.

Growing Glass Gem corn can be a rewarding experience for gardeners and farmers alike. The plants require similar care to other corn varieties, with attention to proper spacing, watering, and soil fertility. Once harvested, the corn can be dried by hanging the ears in bundles in a cool, dry location. This preserves the corn for long-term use as a unique decoration or for eventual processing into popcorn or flour.

History and Origin of Glass Gem Corn

Glass Gem corn emerged from the dedicated work of two individuals who sought to preserve and revitalize heirloom corn varieties. Their efforts led to the creation of a visually stunning and genetically diverse corn that captivated gardeners worldwide.

Carl Barnes and the Heirloom Seed Revival

Carl Barnes, a part-Cherokee farmer in Oklahoma, began the journey of Glass Gem corn. In the 1970s, he started growing older corn varieties, focusing on those with vibrant, translucent colors. Barnes had an exceptional talent for selecting and saving seeds from cobs with the most striking hues.

His work aimed to reconnect with his Native American heritage through corn breeding. Barnes cross-pollinated various traditional corn types, gradually developing more colorful and diverse ears. This process allowed him to recover varieties that had been lost to many Native American tribes over time.

Greg Schoen and the Seed Saving Journey

Greg Schoen, a fellow seed saver, met Carl Barnes in 1994. Impressed by Barnes’ colorful corn varieties, Schoen began a collaboration that would lead to Glass Gem corn. Barnes gifted Schoen seed from his most vivid and diverse corn cobs.

Schoen continued to grow and select the most colorful corn specimens, further developing the variety. In 2005, he began calling it “Glass Gems” due to its jewel-like appearance. Schoen shared the seeds with Native Seeds/SEARCH, a non-profit seed conservation organization, in 2009.

Native Seeds/SEARCH grew out the corn and offered it to the public in 2012. Photos of the kaleidoscopic corn quickly went viral on social media, sparking widespread interest in this unique heirloom variety.

Cultivation and Growth

Glass gem corn cultivation requires specific conditions and care for optimal growth and yield. Proper soil preparation, planting techniques, and ongoing maintenance are crucial for success.

Soil Types and Requirements

Glass gem corn thrives in well-draining, nutrient-rich soil. Loamy soil with a pH between 6.0 and 6.8 is ideal. Before planting, incorporate compost or aged manure to improve soil structure and fertility.

Sandy soils may require additional organic matter to retain moisture. Clay soils benefit from amendments to improve drainage. Conduct a soil test to determine specific nutrient needs.

Adding a balanced fertilizer before planting can boost initial growth. Aim for a ratio of 10-10-10 or similar. Work the fertilizer into the top 6 inches of soil.

Planting Glass Gem Corn

Plant glass gem corn seeds directly in the garden after the last frost date. Soil temperature should be at least 50°F (10°C) for successful germination.

Space seeds 4-6 inches apart in rows 30-36 inches apart. Plant seeds 1-2 inches deep. For better pollination, plant in blocks of at least 4 rows rather than single long rows.

Water thoroughly after planting. Seedlings typically emerge in 7-10 days, depending on soil temperature and moisture.

Growing Season Considerations

Glass gem corn requires a long growing season of 100-120 days to reach full maturity. Plan accordingly based on your local climate and first frost date.

In cooler regions, start seeds indoors 2-3 weeks before the last frost date to extend the growing season. Use biodegradable pots to minimize transplant shock.

Provide wind protection in exposed areas. Strong winds can damage tall corn stalks and reduce yields.

Watering and Care

Consistent moisture is crucial for glass gem corn growth. Water deeply once or twice a week, providing 1-1.5 inches of water per week.

Use mulch around plants to conserve moisture and suppress weeds. Organic mulches like straw or grass clippings work well.

Side-dress plants with nitrogen-rich fertilizer when they reach knee height and again when tassels form. Apply fertilizer 6 inches from the base of plants and water in thoroughly.

Three Sisters Planting Scheme

The Three Sisters method combines corn, beans, and squash in a symbiotic planting arrangement. This traditional technique can benefit glass gem corn growth.

Plant corn in mounds, with 4-6 seeds per mound. Once corn reaches 6 inches tall, plant pole beans around the base. The beans use corn stalks for support and fix nitrogen in the soil.

Plant squash between corn mounds. Squash leaves shade the soil, retaining moisture and suppressing weeds.

This method maximizes space and improves overall garden productivity.

Transplanting Techniques

If starting seeds indoors, transplant seedlings when they reach 4-6 inches tall and outdoor temperatures are consistently above 50°F (10°C).

Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days. This process reduces transplant shock.

Dig holes slightly larger than the root ball. Place seedlings at the same depth they were growing in containers. Water thoroughly after transplanting.

Protect young plants from pests and harsh weather with row covers or individual plant protectors.

Harvesting Glass Gem Corn

Harvest glass gem corn when husks turn brown and dry. This typically occurs 20-30 days after silk turns brown.

To test for readiness, peel back a small section of husk and press a kernel with your fingernail. If it leaves an indentation, the corn needs more time. If the kernel is hard, it’s ready for harvest.

Cut ears from stalks with pruning shears, leaving a few inches of stalk attached. Remove husks if desired, or leave them on for decorative purposes.

Dry harvested ears in a cool, well-ventilated area for 1-2 weeks before storing or using for ornamental displays.
