Climber Wall Shrub Fruit Edible Annual Biennial

The wild common bean from which a vast number of edible beans have been bred, including all the 'French' beans. They are annual, twining climbers with green tri-foliate leaves, though many selected varieties are dwarf. The flowers are mostly purple, but can also be white or pink. They develop into long slender pods of green, yellow, purple or almost black, and contain seeds - also called beans - which are usually white, but can be patterned or plain in brown, orange, black, red or pink.
