Harvesting: Let the ears dry on the stalks. The kernels are ready for harvest when they are hard and you can no longer leave a mark on them with your fingernail. Before the first fall frost, give each ear a twist until it breaks off. Peel back the husks, then hang the ears in a cool, dark, dry place for 4 to 6 weeks to cure. This is important to prevent mold and to dry to the optimal moisture percentage for popping. (In a perfect popcorn world, that would be 13½–14%.) After that, the cobs are ready for popping or storing. To strip off cured kernels, twist the cobs back and forth to loosen them (gloves are recommended).

Colorful display and delicious popcorn

The Glass Gem corn performed quite well despite an intense drought last year. They are much slimmer and shorter than the Wachichu Flint I have grown in the past, but were more prolific in a small plot. Try to let the corn go as long as possible to achieve deeper color. Those I picked a week early were pale and not so glassy like those I picked later. The corn all seemed disappointingly pale when first picked, but the colors appeared over the drying period. The blue in the corn is more in the gray spectrum, but the purples, reds and golden yellows were gorgeous! After using as autumn decorations inside the house, I shelled most of the ears for popcorn. They popped up bright white, light as air on the tongue and had a richer flavor than any store-bought popcorn offers.

I was really hoping this corn would grow. I love popcorn and this would have been very cute to leave out for decoration but none of the seeds grew for me this year.
Owner Response: Thank you for taking the time to share your experience. Corn does take quite warm soil temperatures (over 65 degrees F) to germinate well and as a large seed, it can rot more easily in wet, cool soil. We will be in touch shortly to share some more tips for corn germination.

Amazing colored corn

I grew the Glass Gem corn for the first time. It turned out great. I got 30 beautiful ears from 30 stalks all with different colors and patterns. I will grow again next year.
