적화강낭콩-[정명] Phaseolus coccineus L.

Phaseolus coccineus, known as runner bean, scarlet runner bean, or multiflora bean, is a plant in the legume family, Fabaceae. Another common name is butter bean, which, however, can also refer to the lima bean, a different species.

It is grown both as a food plant and an ornamental plant.

Description

 

This species originated in the mountains of Central America. It was most likely cultivated in the highlands of Mexico and Guatemala around 2000 BC. Most varieties have red flowers and multicolored seeds (though some have white flowers and white seeds) and are often grown as ornamental plants. The vine can grow to 3 metres (9.8 ft) or more in length, its pods can get to 25 centimetres (9.8 in), and its beans can be up to 2.5 centimetres (0.98 in) or more.

It differs from the common bean (P. vulgaris) in several respects: the cotyledons stay in the ground during germination, and the plant is a perennial vine with tuberous roots (though it is frequently treated as an annual in colder climates).

The knife-shaped pods are normally green; however, there are rare varieties bred by amateurs that have purple pods. An example of such a purple-podded runner bean is 'Aeron Purple Star'.

Runner beans have also been called "Oregon lima bean", and in Nahuatl ayocotl or in Spanish ayocote. Runner beans, like all beans, contain the toxic protein phytohaemagglutinin and thus should be cooked well before eating.
