Well, if you look at Trident Seeds the guy(s) actually travels round to different villages and collects the seeds. He shows the plants in their native habitats and explains the history and aromas etc... I used to follow their ig acct before when they were Landrace Mafia just for the cool info and pics.
Don't get me wrong, I don't know them and I can't judge them (after all I have landrace seeds too), it's just that I see an explosion of "seedbanks" of local varieties, generally all the same, and it seems a bit suspicious .....
