Anyone growing runner beans for food?

I have grown pole and bush beans for years. Both of these are variants of the common bean, Phaseolus vulgaris.

Just recently, I started reading about runner beans, Phaseolus coccineus.

Runner beans produce edible pods and beans in the pod, grow fairly tall on supports, and have more colorful flowers than common beans.

Best of all, runner beans are an outbreeder. While common beans usually self-fertilize and produce near-clones of themselves, runner beans cross with other runner beans and therefore can adapt faster to their environment. It should be easier to create a landrace of runner beans than of common beans.

However, some of the information I have read on runner beans seems contradictory.

For example, some sources say that runner beans are perennials, while common beans are annuals. But other sources say they must not be planted out until all danger of frost has passed. I'm have trouble getting my mind around that.

Has anyone here had success growing runner beans as a food crop?
