These are the companies that I have purchased from on a regular basis (in addition to the local plant nurseries and stores that enjoy my business). Disclaimer: I do not have any partnership with these companies, I just get their catalogs and like them. Your milage may vary. Unless otherwise noted, they offer free print catalogs that you can request online.
I've started going through and identifying the companies that specifically indicate that they are non-GMO and have signed the Safe-Seed pledge, but at present, please verify for yourself.

The goal of Heirloom Onions is the preservation, propagation, and reintroduction of unusual and often culturally significant Allium varieties that have–or have almost–disappeared from the market. The onions they grow are perennials, meaning that they can be harvested and replanted every year, or that they can be left in the ground to re-sprout in the summer or fall.
