Product Details
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.
