I have three Lilies. They all have a green bumpy pod inside the flower. Can I take these out and replant them?
Absolutely you can grow more Lilies from the seeds, just be aware that it requires a little more effort.
You didn't mention what kind of Lily you have, so here are some articles that may help you:
If you have a different kind of Lily, you should know that Tiger Lilies and "Day" or "Ditch" Lilies, as well as many other types of Lilies, can be started from the rhizomes (tubers) in the ground. Good luck!
