Inspired by the free and open source software movement that has provided alternatives to proprietary software, the Open Source Seed Initiative (OSSI) was created to "free the seed"--to make sure that the genes in at least some seeds can never be locked away from use by intellectual property rights. In other words, Open Source varieties and any varieties bred from them are part of a protected public commons, free for all to grow and breed with as they see fit. Since so many varieties nowadays have been patented or otherwise protected by intellectual property rights (removing them from the pool of breeding stock), Open Source seed has become a critical tool for ensuring that public plant breeders have the genetic resources to continue developing new varieties. To this end, the OSSI Pledge asks breeders and stewards of crop varieties to pledge to make their seeds available without restrictions on use, and to ask recipients of those seeds to make the same commitment. High Mowing has been a proud partner of OSSI in developing the framework for Open Source seed. We strongly support the work they’re doing to create a pool of Open Source varieties, to connect farmers and gardeners to suppliers of Open Source seed, and to inform and educate citizens about seed issues. To support OSSI, High Mowing is proud to launch our NEW Open Source Seed Collection! By purchasing these or any other Open Source seeds, you are agreeing to the OSSI Pledge:
You have the freedom to use these OSSI-Pledged seeds in any way you choose. In return, you pledge not to restrict others’ use of these seeds or their derivatives by patents or other means, and to include this pledge with any transfer of these seeds or their derivatives.
