Bean Cross-Polination

13 years ago

OK, I'm looking for some clarification as I plan my garden. I do understand that lima beans and yard long beans will cross-polinate. I had planned to plant my Scarlet Runner on the same trellis as my yard longs, but I think Scarlet Runner is a lima, right? So I guess I can't do that.

I have a lot of different bean seed that I just wanted to try, but I want to save the seed. So will the snap, string and non-lima dry bean varieties cross-polinate each other, too? If I have rattlesnake beans planted near yin-yang, for instance, am I not going to get true seed?
