Oddly enough, I've seen bean varieties cross quite frequently. The problem was a combination of two droughty years and a huge population of bumblebees when the local honeybees died off. Lacking other food sources, the bumbles really worked over my well-mulched bean rows. Once they even managed to cross a P. vulgaris variety with a P. coccineus, which is supposed to be impossible! Fortunately, the cross usually shows up in the seeds, and I rogue them out. I've tried growing out a few of the most interesting crosses, but they were disappointing.
Then there are sports. Some bean varieties seem particularly prone to this; I guess it's why there are so many varieties of Black Valentine. In fact, I have a sport of this I think I'll grow out for a few seasons and see if it's stable.
