Need Help with ID

This plant was a gift 2 or 3 years ago and we just figured out it is making seeds. Have looked around and can't seem to find it on the flower sites. Maybe somebody here will recognize it. The first picture has pointers to the bloom pods which start out light-green and fade to brown after the bloom cycle. Picture 5 has a first bloom on a new pod. There are generally a dozen or more blooms per pod. The pods finally turn brown and the seeds are easy to remove from the pods by eliminating the chaff that crunching the pods creates. The leave have purple backs (or bottoms as you will) shown pretty well in picture 4. I have tried to brighten the pictures a bit, but picture 4 was taken with a flash. Picture 3 is the whole plant sitting on one of the tables I make. Pot and all, it's about 3-4 feet tall.

Would appreciate any help identifying this one. Seeds are soon to be available.
