True String Beans
I am looking for the names of old green bean varieties that have strings on them or solid sources for this information. Hard to find decent info because of the confusion with so many sources interchanging the terms "string" and "snap" for what are in fact the stringless varieties.
It is my understanding that the first stringless snap bean came out around 1894. If that is correct then I should be able to assume all green bean varieties prior had strings. Logic would dictate that many varieties still had strings after this date until all bean breeders caught up with the innovation. My grandmother still grew true string beans in the 1940's and 1950's, but this could possibly be explained by the simple fact that she may have saved and replanted her own seeds.
Trivia Question: What was the name of the last new variety of true string bean and what was the last year it was commercially available? (I am seeking the answer myself.)
