Phaseolus coccineus ( Black Coat Scarlet Runner Bean )
They are a very large black bean.Pollinated by bumblebees, Soil temperature must be at least 50 Fahrenheit to germinate seeds, They can be reluctant to set fruit if temperatures exceed 90 degrees Fahrenheit. They should be in a fertile soil. They have deep roots. Leaves can sustain a good amount of bug damage. The flowers are tiny.
These were planted May 1, 2015. We have had allot of rain in Missouri. And cooler than normal temperatures. So this has taken 5+ weeks to start flowering. I will update this post as the plant progresses.
