On my Stella D'Oro lilly, the pods had small black shiny seeds. But my Stargazer Lilly, when their pods turned brown and opened , it only looked like brown pieces of paper.

Of course I saved both, but are they viable?

I am addicted to collecting seeds, but don't always know if what I am collecting are truly seeds.Is there a good book available to help me identify seeds?

Sometimes the seeds are so obvious, but othertimes I can't locate them on the plants.

All advice and help will be greatly appreciated.

Am still kinda new to this site, so thanks in advance.
