I've been rummaging for seed sources to see if I can get some landrace breeding going, and ran across a post on Reddit where a lovely person shared a list of seed suppliers with helpful info. I know there is also a grid at the top of this forum, which I found SUPER helpful too, but there is some additional info below. Thought I'd share in case anyone has additional info or thoughts to add!
Below is a copy of the post from Reddit, thanks to r/bellaweather:
[i]So I thought I’d share this is a list I’ve been working on of seed suppliers. I started with who I’ve purchased from in the past and then organized by where are they located (I’m NE zone 6) and started researching- Company history, are they non GMO, are they organic, have they taken the safe seed pledge, and so on.
And this is what I currently have:
