>> Anyone know if beans cross pollinate?
I only know what I read, but that says "mostly not". I found a pretty reliable source, a senior member of SSE.

That link supported my belief that, if you have a ton of bumblebees and no other nectar source, you may get some crossing. However, if this i9s for home use and not breeding or selling, go for it! So what if you have to cut down one F2 plant in 20, or not save F3 seeds from that one plant?

Per www.seedsave.org, "Although, ideally, different varieties should be separated by 150 feet or another crop flowering at the same time,
we rarely observe cross-pollination even when two varieties are grown next to each other."
