Martian Jewels Sweet Corn seed produces corn with unique qualities. Stunning purple plants produce white cobs and pearl-white kernels. This corn is just as decorative as it is tasty; neighbors are sure to comment on this unusual corn. Great for cooking or eating fresh. We like this corn for making tamales, cornbread, and more! The flavor is sweet but not overpowering. Martian Jewels sweet corn is an overall amazing variety bred by Alan Kapuler.
