Then there's the value of greasy pole beans and really wet weather. One year, with 30 days of rain in 34 days during dry down time (the pods, not the weather
), I lost every variety to rot, except one, the one and only greasy bean in the garden. And that one produced about 300 seeds per plant.
The only thing I could figure out is that, perhaps, the slick/shiny pods shed water, and therefore dry better, than regular bean pods
