About

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 can also refer to the lima bean, a different species.

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

Uses

Runner beans were grown as food plants in North America and Europe from the 1600s, and also as ornamentals for their attractive flowers. However, they came to be used primarily as a garden ornamental plant in North America, including for temporary screening. The flowers attract hummingbirds, bees and other insects. In the UK and other European countries – where the vegetable is a popular choice for kitchen gardens and allotments – the flowers came to be ignored, or treated as an attractive bonus to cultivating the plant for the beans.
