I have a bunch of Stella de Oro bee pods. Chances are, I'll let them fall where they are and let nature take its course. I have them mass planted in a nice row, about 10 feet. I have almost 2 acres and so the strip makes a lovely dent in the "field" as seen from the back deck. If any of them make it on their own, I'll see what happens... My collection is small thus far, so I have the space to play with self crossed, bee pods, deliberate crosses, omg-look-what-i-found-at-_____________'s-and-it-was-on-sale!, etc.
So, I'd keep the seeds
But then I keep seeds that I know I'm never gonna find time to plant
...I think I'll check those Stella pods tomorrow... Maybe I'll just keep a few...
