Siskiyou Seeds

They are based in Oregon and specialize in open-pollinated and heirloom seeds. They recently did a collaboration with a co-op seed company based in Catalonia to introduce Catalan tomato varieties traditionally used for pa amb tomàquet (a.k.a. pan con tomate). I had been looking for these seeds for a while now and was delighted to see a US-based seed company working with a Catalan producer.
