The '''runner bean''' (''[[Phaseolus]] coccineus'', [[Fabaceae]]) is often called the '''scarlet runner bean''' since most varieties have red [[flower]]s and multicolored [[seeds]], though some have white flowers and white seeds. It differs from the [[common bean]] in several respects: the [[cotyledon]]s stay in the ground during [[germination]], and the plant is a [[Perennial plant|perennial]] with tuberous [[root]]s (though it is usually treated as an annual).
The green pods are edible whole but in some varieties (the scarlet runner) tend to become fibrous early, and only the seeds within are eaten. The seeds can be used fresh or as dried beans. The starchy roots are still eaten by Central American Indians. The scarlet runner is widely grown for its attractive flowers by people who would never think of eating it.
Runner beans contain traces of a poisonous [[lectin]] [[Phytohaemagglutinin]] and hence must be thoroughly cooked before consumption.<ref>[http://www.scienceyear.com/outthere/index.html?page=/outthere/diner/fatalfoods/index.html Fatal foods]</ref>

''Phaseolus coccineus subsp. darwinianus '' is a cultivated subspecies of ''P. coccineus'', it is commonly referred to as the Botil bean in [[Mexico]].
