Okay here is a very overgrown yard long bean (the really long one) and some that are picked the correct size for eating.
And in this picture the eating size yard long beans are next to my French Gold Fillet Beans wich are the right size for eating.
Yard long beans are strong vines and they have lovely purple flowers. And my pole beans this year are extra pretty also as these French Fillet yellow beans are tender and tasty with light purple flowers.
