Have Yard long Bean seeds to trade. I grow them for the humming birds and the grand children. They are edible in stir fries. The flowers are shaped like sweet pea flowers, medium pink and about the size of a quarter. The beans seem to grow inches every hour on hot humid days. The humming birds will go from flower to flower and then rest on the trellis under a bean leaf. I tried to capture a picture of them but they are just too fast. I have included a picture of them on a trellis of 'pig' wire in the garden.
