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.

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.

What little corn I got was good. Beautiful color good garden accent. Maybe would have done better but got a blight from all the rain. Only thing I didn't like it stains your hands purple when shucked.

The description is wrong, my cobs are purple too. Regular old yellow sweetcorn is so boring to eat after enjoying this fine sweetcorn! Can't wait to plant more next year! Can't wait to make purple tamales!

Beautiful corn.

These corns are very attractive and tastes good. While the kernels are white when raw, the anthocyanin is leaked from the cob when you cook it and highlighting the kernels with purple. It look beautiful in a corn salad. The bare cobs are very purple. While harvesting the corn ears with bare hands, your palms will be temporarily stained with purple.
