I love Aponogetons! If I only had the room, I'd devote entire aquariums to their cultivation!
How you propagate an Aponogeton is going to depend on the type of Aponogeton.
Some of the plants, like A. crispus (which I suspect you have) are going to self pollinate, form seeds and propagate themselves. Some other Aponogetons, like A. ulvaceus need to be cross pollinated with another A. ulvaceus, like many terrestrial plants (ie. Corn). Then there is A. undulatus. That Aponogeton rarely flowers. Instead, plants form on what would normally be flower stalk, kind of like Ecinodorus plants do. Those plants will remain on the stalk until they are clipped of, or a tuber forms and the plant releases itself naturally.
Then there are slight variations within the Aponogetons based on the color of the flower. Once again, A. ulvaceus. A. ulvaceus plants with violet flowers are self fertile, and A. ulvaceous plants with white/yellow flowers need to be self pollinated.
The flower color variations also apply to the rest period, or lack of rest period, required by some of the Aponogetons.
