This is the true "Yard Long" bean, with light-green pods 38" long, with black beans. The long vines set heavy yields of these delicious pods that will amaze your friends! LOng beans should be lightly fried; not boiled. They have superior flavor to common beans. This variety was collected from a Taiwanese immigrant in the 1970's.
