Are you asking about what variety of long (asparagus) bean to grow ?

I've grown "Red Noodle" before. Had it growing up an arched trellis and made long red bean pods hanging down about a couple of feet long . It's used in some Asian dishes. I didn't particularly care for the taste of them but probably wasn't cooking them right. They ended up being a magnet for aphids.

I don't know of anybody growing long bean "cultivars".

Looks like you grow in a green house/high tunnel arrangement ?

I don't have any to trade, but I grew a green, black seeded version. They're actually a cow peas Rick, and I think best in stir fry. The don't mind the heat and for a long time I got volunteers every year.

And yes, like my cow peas, they draw aphids.
