Two yeas ago health problems interfered with getting out to the garden to collect as many healthy seed as I wanted. I usually try to save enough to cover two years "just in case". Then last year I did not stop harvesting my beans for fresh eating & canning soon enough, which meant that I got only a handful of mature seed, and quite a few that are not well shaped and probably won't produce good seedlings. I don't have enough seed to cover even one season's planting needs.

So I need to buy more seed. But I'm not sure what variety I'm looking for. It's been too long since the original purchase.
The bean I'm looking for is a Romano pole type-- flat ,very long pods which stay tender to as much as 10 inches. It's seeds are white. The margins of the pods are pretty straight rather than wavy from the beans, I think it is Hilda or Helda, but I could be wrong.

Does that sound like Hilda?

If so, where is a good place to buy? I will need about 120 seeds.
