The yard-long, or asparagus bean (Vigna unguiculata subso. sesquipedalis), is a close relative of the southern pea. It produces pods up to 3 feet long. The plants are indeterminant (vining) and require support. The pods are tender when young and are frequently used as snap beans. For this use, harvest them when the pods are partially developed and before seed enlargement. For shelling, harvest them when the seeds are full size but still immature. They may also be shelled when fully mature (dry).
