Sweet Corn, Double Red (Organic)

Zea mays. Sweet. 85 days.

Double Red Sweet Corn is a superb addition to the list of cool, purple vegetables. Normal sugary (SU) kernels are sweet and richly flavored, but the real coup of Double Red is the ridiculously dark red color. The kernels are so red that they can turn your fingers purple when eating it. Certainly a culinary necessity for those of us trying to “eat the rainbow.” Red hue varies a little from ear to ear with many so dark red they seem almost black-purple. This rare color in sweet corn comes from the anthocyanin pigments that are also seen in the plant’s leaves. A natural source of anti-oxidants, anthocyanins are also anti-inflammatory. Plants are 5-7′ tall with 1-2 ears per stalk. We have heard that when dried and ground, it makes a delicious purple corn bread, but we eat them all fresh and haven’t tried this yet. Using traditional plant breeding methods, Double Red was bred by Dr. Alan Kapuler of Peace Seeds in Corvallis, Oregon. It is the culmination of 25 years of breeding work by Peace Seeds and 8 years of collaboration with Dylana Kapuler and Mario DiBenedetto of Peace Seedlings.


Corn does best when direct sown 1” deep, spaced at 18” centers. Plant when danger of frost has passed, after soaking seed overnight. For optimal pollination plant in blocks of 100. Sweet Corn can be slow growing at first due to the shrunken kernels having less energy to get started. Cover with row cover in cool weather or plant later in the spring when soil temperature has reached 60° F.

Seed Saving

Harvest for seed when stalks are brown. Pick cob, fold husk back, and leave inside to dry completely. Remove kernels by rubbing two cobs together, or by hand. Test for dryness with a hammer; dry kernels shatter and moist ones squish. Isolate from other corn by 1/2 – 1 mile or two weeks for time isolation.
