Flowers have bulbs and seeds?

I have always had flags (iris) growing around the house and have always dug up the bulbs, separated them and re-planted them to get more of them. Recently I've been told that the pod that develops after the flower has dropped can also be planted and will grow into a new plant. I've been around these flowers all of my life and never noticed this happen naturally. Does anyone know what the deal is?

Flowers have bulbs and seeds?
I always deadhead my Iris before they have a chance to form pods. Just so you're clear, Iris don't grow from bulbs. They ggrow from rhizomes.



Here's a site that discusses Flag Iris and their seedpods at least a little bit.
