CERTIFIED ORGANIC! Oklahoma native Carl Barnes selected the stunning Glass Gem Organic corn seeds from several traditional heirlooms known for their beauty. Words don't do justice to the multicoloured, translucent, gem-like kernels on these amazing cobs. The plants are sturdy and grow 6-8' tall, with several 18-20cm (7-8") long ears. The kernels can be popped or ground into flour, but they're almost too beautiful to part with. Consider starting this one indoors, as it has a long maturation. The kernels take on these extraordinary colours as they dry so they make exceptional autumn displays. No two cobs are identical.
Matures in 105 days. (Open-pollinated seeds)
These big plants will grow in almost any soil, but getting the cob to mature is another matter. The maturity of the ears (cobs) is not controlled by the size of the plant, nor by day-length, but by the accumulated heat the plant has had while it grew. They call this the “heat units”. Only temperatures above 50 F count after the last killing frost of spring. Temperatures above 50 F add up to create the heat units. Corn plants generally grow very tall, and will shade other vegetables. Some plants will benefit from this shade, such as lettuce, but heat-loving plants must be placed so that the corn does not shade them. This heavy-feeding plant also provides a stalk for plants such as Pole Beans. Follow along with this handy How to Grow Corn from seeds Guide and grow food.
