These bush green beans have been champs, continually producing even though they look like they should die (and it's mid-August in Zone 5, having had some massively warm spells).
However they have looked like this for a long time now, but they keep flowering and producing - we've gotten about 20 pounds of beans from ~20 linear feet of them.
Is this something that is common to beans? Or is this just them trying to die due to heat? I understand beans aren't exactly all-summer producers normally.
