There is a vine growing over my sister's porch which has pods unlike any I have seen before.
The pods (they are not present yet - the plant is still blooming) are large and fat, perhaps several inches long and over an inch wide. They are a blueish-green color, if I remember right.
I am attaching pictures of the flowers (which are in bloom right now) and leaves.
The plant is growing in Bellingham, Washington.
