runner bean Phaseolus coccineus, is so called because it is a climbing plant. It has a stronger flavour and more showy flowers than the green ‘French bean’ (see haricot bean) with which it is sometimes confused.
The runner bean originated in C. America, possibly Mexico. American Indians still eat the starchy roots, besides the young pods and dried seeds which are generally consumed.
The ‘scarlet runner’, named for its bright red flowers, was introduced to England by Tradescant, the gardener of King Charles I. At first it was grown for its flowers which were often used in bouquets. The flower colour is a sign of the colour of the seeds, which range from white through pink to a deep purple. Mottled seeds are common.
