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.

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.

Martian Jewels sweet corn

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.

Best darn sweetcorn

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.

Spectacular

These are pretty enough for the flower garden and make delicious sweet corn. Mine we stunted from lack of water, but looking forward to growing again next year with irrigation. Striking deep purple leaves, ears, and cobs with creamy white kernels.

Great corn

This was so fun to grow! The stalks got about 6' tall, had 1-2 ears each. Corn was amazing - very sweet. Fun to watch grown as it grew so quickly. One my kids especially enjoyed as corn is one of their favorite veggies to eat.

Loved the color of the corn husk, but the corn was not very sweet and did not produce very well in our area. Very spotty - I have grown other sweet corn here and it has done well, so I know it's not the soil.

Very slow growth

I planted this at two different addresses. Neither did well at all, we had no harvest. Plants were puney and poor color.

Owner Response: Hi Robin, Thank you for sharing your experience. It sounds like the seeds performed just fine however the environmental conditions could be improved. Corn is very "plastic" meaning its performance is dependent upon environmental conditions, showing differences in height, plant appearance, and yield based on soil, water, sun, and nutrient quality. A soil test is a great way to see how your soil can be improved for crops like corn which require a lot of water and nutrients. We are always happy to help you troubleshoot growing issues, please feel free to contact us.
