HOW TO GROW CORN, FLOUR
Corn takes about 14 days to emerge from 50°F soils but only about 5 days to emerge at 70°F. Plant about mid May in the Midwestern U.S., as early as mid April in milder climates. Can direct seed as early as mid February with row cover in mild temperate climates. In regions with short growing seasons, start indoors two plants per cell 3-4 weeks before last frost, plant out after frost. Some soak seeds in water tepid for an hour or two before planting. If cool and wet, plant shallow 1 to 1-1/2”. If hot and dry plant 2–3”. Plant in blocks to ensure the best wind pollination. Do not soak seeds before sowing. Open pollinated corn varies more than hybrid corn. Soil pH 5.8-7.0. Hardiness zones 4-8. Annual.

Riverspirit Rainbow Flour Corn has a rich history of being grown as a staple food on homesteads in northern California and Oregon for decades. Legend has it that it was originally gifted to homesteaders from the Navajo grandmothers at Big Mountain Arizona. It’s a blend of Hopi White, Anasazi, and Hopi Blue native flour corns that is perfect for corn bread, corn cakes, tamales, and masa. Plants grow 7-10’ tall, and each plant produces 1-2 large ears of colorful corn. It’s a beautiful surprise shucking the mature corn and finding what rainbow jewels await inside.

Corn has been cultivated for at least 5,000 years probably originating in the lowlands of western Mexico. Maize geneticists believe that 90 percent of breeding work in corn had already been done by the time Columbus arrived to find large fields of corn being grown on the island of Hispaniola in 1492. Modern sweet corn most likely descends from flint corns of the northeastern U.S. The sweet corn gene (sugary1, su1) was selected by Native American in at least four additional locations: highlands of Peru, central plateau of Mexico, northwestern Mexico southwestern U.S. and the northern Great Plains. Corn types are sweet corn, starch, parch, flint, dent, popcorn and ornamental. Corn types are sweet corn, starch, parch, flint, dent, popcorn and ornamental.
Native Americans planted corn when the gooseberry bushes were almost in full leaf. They cultivated about 18” diameter, pulled up last year’s dead roots in the spring and formed a hill. Six to eight seeds were planted in the center 9”. Later more earth was hilled up to cover the roots to protect them from the summer sun. Hills were 4’, far enough part so the leaves of mature plants would not touch. Beans and squash were planted after the corn. Beans were planted diagonally between the corn hills across the whole field. Squash was planted in rows outside to separate from the neighbor’s field. Four squash seeds were planted in pairs into opposite sides of a 15” diameter hill.
