This season I'm trying Tennessee Green Pod for the first time. It was listed as a 50 day bush bean but I soon noticed what looked like vines starting. I did some internet sleuthing and came across something that said that this bean "has semi-runner tendencies". That caused me to put a piece of fencing behind them and sure as shootin' they're climbing it. It will be interesting to see how far they "run".
It's now 26 days from germination and they're flowering. If this really is a runner bean and takes the heat, I'll let you know. They just might finish before the real heat sets in though, so I might plant more in another bed for a later finish to test heat tolerance.
Got 'em from Shumway:
