Thr Scarlet Runner has been in this country for a long time, but mostly
grown
as an onamental. There are other cultivars of runner beans, Phaseolus
coccineus
,that are improved as far as production is concerned. All that I have
encountered do not set well in hot weather. They prefer climate like
northern
Europe.

I think you must have your beans mixed up.

The name "Scarlet Runner" is the name that applies to phaseolus coccineus.
Phaselos from greek for bean and coccineus is 'scarlet' in Latin..
