Sassi, I grow the white flowered variety 'White Lady' and have to say that after many years experience, is the best runner bean introduction ever.
This is the seed merchant description, which I can vouch for as being accurate:
" A premier variety in every way! Vigorous, high yielding plants produce the most tender, thick, succulent pods you have ever tasted. The delicious long, mid green beans of Runner Bean ‘White Lady’ are stringless with a wonderful smooth texture. These white flowered plants are less prone to bird attack than their red flowered cousins, and set well, even in high temperatures, guaranteeing a plentiful crop. Height: 3m (10’). Spread: 30cm (12”)."
