About 30 years or more ago, there was a variety of bunching onion on the market called Beltville Bunching. It was an amphiploid of Allium cepa and A. fistulosum. I really liked it. But I have moved a few times since then, and long since lost it. I looked for it in seed catologs for some years and not found it nor anything like it. Anyone have it or have an idea how to find it? I have a couple of A. fistulosum varieties, but I don't like those as well.
That's definitely been around for awhile. USDA seed bank, ARS-GRIN, had it donated in 1966. They still maintain it, number is PI 546228. If you can sort out how to request seeds, distribution is 50 seeds.
