Oklahoma native Carl Barnes selected the stunning Glass Gem from several traditional heirlooms known for their beauty. Words don't do justice to the multicolored, translucent, gem-like kernels on these amazing cobs.
The plants are sturdy and grow 6-8' tall, with several 18-20cm (7-8") long ears. The kernels can be popped or ground into flour, but they're almost too beautiful to part with. Consider starting this one indoors, as it has a long maturation. The kernels take on these extraordinary colors as they dry so they make exceptional autumn displays. No two cobs are identical.

Starting
Do not soak corn seeds prior to planting. Plant 2-5cm (1-2″) deep (shallower for sh2 seed or in cool soil). Sow seeds around 7.5cm (3″) apart, in rows 60-90cm (24-36″) apart. Because corn is wind pollinated, plant in a dense block of at least 4 rows, rather than in single rows. This increases the chance of corn pollen, which emerges from male flowers at the growing tip, to fall down onto the receptive female silks that extend from each corn cob.
Timing
Direct sow in late spring. If the soil is not warm enough, seeds often rot before sprouting – especially when not treated with fungicide. Untreated corn seeds should be planted only when the soil has warmed up above 18°C (65°F) – warmer for super-sweet (sh2) types, and even warmer for a good stand. Use a soil thermometer. If spring weather is cold, consider planting in flats or individual pots, indoors with bottom heat, for transplanting. Seeds should germinate in 7-10 days. If it rains after planting and corn does not emerge, just re-plant the area.
Harvest
When the silks at the end of an ear are a dry brown, the cob seems to start to droop, and the kernels release milky juice when cut.
