Organic 'Glass Gem' popcorn
Organic 'Glass Gem' popcorn (Zea mays) from Gaia seed company, a legendary multicoloured corn with translucent, jewel-like kernels
'Glass Gem' corn is one of the world's most celebrated heirloom varieties, created by Carl Barnes , a Cherokee farmer from Oklahoma who patiently selected native lines to preserve their beauty and history. Each ear is a living work of art: translucent , vibrant kernels in every shade of amber, turquoise, purple, coral, jade, and pearl . No two ears are alike, making this variety particularly magical both in the garden and when dried for decorative purposes.
The robust plants, reaching 6 to 8 feet in height , bear several 7- to 8-inch ears, suitable for popcorn —deliciously crunchy and slightly sweet—or for fine, colored cornmeal . An open-pollinated variety, it requires a relatively long growing season, hence the advantage of starting it indoors in northern climates.

Farming method
Sow directly when the soil reaches 19°C (66°F) , or start seeds indoors to enjoy the entire season. Sow seeds 2.5–5 cm (1–2 inches) deep. Plant in full sun (level 3) with ample watering (level 3). Space plants 20–25 cm (8–10 inches) apart and rows 60–90 cm (24–35 inches) apart. For good pollination, sow in clumps rather than long rows. Germination takes 5–8 days at temperatures between 15–32°C (59–90°F) (optimum 29–90°C / 84–90°F).
Harvesting and preservation
Harvest when the silks have dried , the kernels are plump , and they have reached their final color . To dry the ears: fold all the husks towards one end, tie them together, and then hang them in a dry, warm, and well-ventilated place for a few weeks. The colors become even more vibrant once dry.
