Flint Corn
Atomic Orange Corn is a stunning heirloom flint corn that delivers exceptional nutrition packed into early-maturing ears. Bred over 30 years by Ed Schultz of Bozeman, Montana, this open-pollinated variety ranks among the most protein-rich heirloom corns ever studied, while its remarkable beta-carotene content supports vision health. The brilliant orange ears emerge remarkably early in the season, typically within 60 to 80 days, making it reliable even in shorter growing regions (zones 2 to 12). Its combination of deep nutrition, striking appearance, and quick maturity makes it a standout choice for gardeners seeking substance alongside beauty.

This is a protein powerhouse with roots in serious corn breeding. Ed Schultz spent three decades perfecting Atomic Orange, and Baker Creek's 2018 nutritional study confirmed its place among the highest-protein heirloom corns available. The orange kernels deliver exceptional beta-carotene levels, and the variety matures so quickly that even gardeners in zone 2 can reliably harvest full ears. You're growing the result of decades of deliberate selection for both flavor and food value.
As a flint corn, Atomic Orange is well suited to grinding into cornmeal and flour, where its high protein content and vibrant color make it exceptional for polenta, corn bread, and traditional grain dishes. Its nutritional profile, particularly the beta-carotene content, makes it valuable for anyone seeking to add nutrient-dense whole grains to their diet. The kernels can also be dried and popped like popcorn or prepared fresh as sweet corn, though its flint corn classification suggests it shines brightest when fully mature and dried.
Direct sow seeds after the last frost date when soil temperature reaches 60°F or warmer. Plant seeds 12 inches apart and roughly 1 to 1.5 inches deep.
Harvest ears when the husks turn brown and dry, typically 60 to 80 days after planting. For eating fresh, pick when kernels reach their full size. For drying (the traditional use for flint corn), allow ears to remain on the stalk until the husks become papery and the kernels harden completely, which may extend several weeks beyond the minimum maturity window.

“Atomic Orange emerged from the dedicated work of Ed Schultz, a gifted corn breeder based in Bozeman, Montana. Schultz spent 30 years developing this variety, carefully selecting and crossing plants to achieve his vision of a corn that would excel nutritionally while remaining accessible to home gardeners. The result is an open-pollinated heirloom that captures both the nutritional density of traditional corn varieties and the early maturity needed for short-season growing. Baker Creek Heirloom Seeds now stewards this variety, having validated its exceptional protein and beta-carotene content through their own 2018 research study.”
