That's a *really* good question. I do know that Scarlet Runner beans bloom on side-shoots and I've gotten the impression they get better production up higher, but it may be that those bean flowers get more pollinator attention? My reality is that if beans vines run out of support, they just topple sideways and keep growing.
Will they flower a second time low down, or does future harvest depend on the individual vines growing longer and setting more flowers?
