The runner bean (Phaseolus coccineus, Fabaceae) is often called the scarlet runner bean since most varieties have red flowers and multicolored seeds, though some have white flowers and white seeds. It differs from the common bean in several respects: the cotyledons stay in the ground during germination, and the plant is a perennial with tuberous roots (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.
This species originated from the mountains of Central America.
Phaseolus coccineus subsp. darwinianus is a cultivated subspecies of P. coccineus, it is commonly refered to as the Botil bean in Mexico.
The runnerbean (Phaseolus coccineus, Fabaceae) is often called the scarletrunnerbean since most varieties have red flowers and multicolored seeds, though some have white flowers and white seeds.
It differs from the common bean in several respects: the cotyledons stay in the ground during germination, and the plant is a perennial with tuberous roots (though it is usually treated as an annual).
Runnerbeans are best sliced using a small tool which also removes the sides (the strings) on varieties that have them.
The scarletrunnerbean is a large showy plant that produces numerous clusters of beautiful scarlet blossoms that later mature into beans that may be utilized in the same manner as snap beans.
The scarletrunnerbean is indigenous to Central America and early explorers brought it to England where, until the 19th century, it was used strictly as an ornamental plant.
Scarletrunnerbeans are grown in the same manner as pole beans.
