The best pole beans I've grown is Smeraldo, from Park seed.

Huge long green flat pods that remain tender even after the pods buldges up. I am growing them all for seeds this year, no harvest, so I can share the seeds with people.
I am also growing Liberty runner beans from Robinson's from UK.

I paid more for shipping than the 10-seed package, but they are outstanding. My beans are about 1 foot long, not the 2 they claimed. but they are early and vigorous, outproducing my regular Scarlet runner by far.
I grew Purple Peacock and Rattel Snakes as well. I like them for giving away to friends for their unique looks.
I wonder if anyone wants to do a small scale seed swap for the beans. Trading the winners in our gardens.
