This variety is an Open Source Seed Initiative pledged variety!

"Today, only a handful of companies account for most of the world’s commercial breeding and seed sales. Increasingly, patenting and restrictive contracts are used to enhance the power and control of these companies over the seeds and the farmers that feed the world.

Patented and protected seeds cannot be saved, replanted, or shared by farmers and gardeners. And because there is no research exemption for patented material, plant breeders at universities and small seed companies cannot use patented seed to create the new crop varieties that should be the foundation of a just and sustainable agriculture.

Inspired by the free and open source software movement that has provided alternatives to proprietary software, OSSI was created to free the seed – to make sure that the genes in at least some seed can never be locked away from use by intellectual property rights."  From the Open Source Seed Initative website.



Intermountain-west pest concerns:  Earwigs can be a problem in irrigated gardens based in desert climates.  They are naturally aquatic, and attracted to irrigated landscapes, which most of our gardens are.  In corn, earwigs feed heavily on corn silks during the silking stage.  This can reduce successful pollination, and lead to ears with missing corn kernels where pollination failed.  Earwig damage to silks is easy to overlook, as the silks continue to elongate.  Silks that have been damaged by earwigs have browning on the ends of them. Alternatively, since earwigs are nocturnal feeders you can go out with a headlamp at night to see if they are feeding.  Get ready for a creepy crawly horror show though, you might see more freaky earwigs in one spot than you ever thought possible!

Option one:  In varieties where the husk wraps tightly around the growing silks of a corn ear, earwigs have a hard time damaging much of the silk, so these varieties might be best for organic production in areas where earwigs are a problem.  Giving Ground Seeds is currently working on assembling a list of varieties which exhibit this trait.

Option two:  Alternatively, you can spray the corn silks at dusk with Spinosad, an OMRI approved pesticide which is easy to find at any nursery or garden center.  The earwigs will feed on the silks and die.  Pollinators can die from spinosad too though, so it's imperative spray take place at dusk and be concentrated on the silks.
