I have been starting seeds both for my own garden and the Soil&Water volunteer garden. I wanted to stay as organic as possible and wanted to find a source that I can trust. It was important to me that the seeds are non-GMO and hopefully not owned by Monsanto (Seminis). I did a lot of research and found a number of resources but the information out there is extremely confusing. If you start digging, many organic gardening resources are actually owned by Seminis.
After a lot of research, I was relieved to learn that a local nursery, Summerwinds, appears to have only non-GMO seeds from two companies, Lake Valley Organics and Botanical Interests. Both of which appear to not be owned by Monsanto or Seminis. Lake Valley Organics also has taken the safe seed pledge. I also visited Baker Creek Heirloom Seeds (rareseeds.com) in Petaluma, CA. That experience was awesome. They are located in this old historic building and have more seeds than you can imagine along with books and gardening tools. I was definitely inspired and walked away with a bunch of great seeds and a book on fermentation.
