Blue Mountain Flint Corn - Organic


Blue Mountain Flint Corn - Organic

Zea mays
(88 days) Open-pollinated. Those of you who prefer flint corn for food can now have it in blue and enjoy the health and healing benefits of the anthocyanins (antioxidants). Flint corn has a layer of hard starch on the outside which grinds up coarser and makes a somewhat grainer flour than the softer flour corn does. This grainier texture makes it better for grits, polenta, hominy and, arguably, for cornbread. When grown in wet climates, flint corn’s hard outer layer of starch can resist mold better than soft flour starch can.

This predominately dark blue, 8-rowed flint corn grows very much like Painted Mountain Corn which is 50% of its ancestry. The other half of its ancestry comes from a composite of 20 of the fastest maturing New England flint corns. The short efficient native-type plants produce long, narrow 8-rowed ears which dry quickly in a short growing season. Fast maturity is one of the best tools for eluding climate disasters. And its diverse ancestry, an alleviator to the inbreeding of so many flint corns, will allow for further selection to adapt to where you live. 2022 Fedco introduction. Independent Breeder.

¼ cup pumpkin seeds
¼ cup sesame seeds
¼ cup flax seeds
¼ cup olive oil

  1. Heat 1¼ cups of water to boiling.

  • About 85–275 seeds/oz. 1 oz packet sows 25 ft, 1 lb sows 400 ft.
  • Seeds per packet vary, open-pollinated selections average 100 seeds/oz, normal sugary varieties 140 seeds/oz, and SE cultivars with shrunken seeds 150-160 seeds/oz.
  • Days to maturity are from emergence after direct sowing; for transplants, subtract 20 days.

Culture: Untreated sweet corn seed will not germinate in cold wet soil. Please be patient and wait till soil warms to at least 60° before sowing, or start seedlings indoors and transplant at 3–6" before taproots take off. Minimum soil temperature 55°, optimal temperature range 65–85°. Tender, will not survive frost. Heavy nitrogen requirements.
