Though the striking color is other-worldly, the flavor of this one-of-a-kind jewel is more traditional—slightly less sweet than modern, very sweet hybrids. It was a labor of love to produce an open-pollinated corn that is loaded with beneficial anthocyanins (antioxidants), thanks to its Native American Hopi blue corn parents. Harvest fresh, or wait a bit longer and the sugar subsides, becoming perfect for breads or chowder, or wait even longer to harvest, and use the dried kernels for flour.

Growing Info

Harvesting: Corn is ready about 3 weeks after the silks appear. Harvest when the silks are brown, but not dried, and the husks are dark green; ears should be plump, and rounded rather than pointed at the tip. To test for ripeness, gently pull back the husk and pop a kernel; the liquid should be whitish; if it is still clear, ears are not quite ready.

    This was a very rewarding first experience growing corn. I would recommend getting a high nitrogen fertilizer. Corn seeds germinated uniformly and well. Plants varied in height, some produced corn some did not get large enough to. Plants are very attractive with green and dark maroon purple features. Corn was smaller but tasted good. I enjoyed both the look of the plant and the edible factor. Best to grow where won’t be affected by strong wind, unless it’s supported. I will grow this again.

    Two and a half months ago, I planted 8 corn seeds hoping to get 4 stalks, and that is what I got. Two are still rather small, but I have hopes for the two larger ones. I have never tried to grow corn before at all, much less in a grow bag, but I followed directions online and on the seed packet religiously, so we shall see...I planted in Epsom Organic Potting soil outside; for the first two months the temps were mild---70s and 80s in the day and generally 20 to 30 degrees colder at night---but for the past two weeks temps here (in southeastern AZ) have been in the high 90s to the low 100s, and it's going to be hotter in the coming week. I am giving the corn about a gallon of water every 2nd or 3rd day, hoping to keep it healthy.

    This is our new family favorite! This was the first time we grew this variety, and it easily became our favorite. It went through a cold front after it's first few weeks of planting, and 3 storms, and it was strong enough to survive through it all without any protection. I just bought more seed packets, and this will be a garden staple!

    The best sweet corn ever. Eat immediately after picking for best flavor. Eat raw or cooked, preferably on a grill with a little salt.
