They say that the pollen matures early and self pollinates the flower even before it opens, so it has no need of being pollinated in the air. I'll be watching to see if this one forms seeds. I think there's another bud on it now.
The big pond (~16') is under construction still and I don't know when it will be done, so I've moved the plant to yet another stock tank--this time a 180G that I had picked up for fish quarantine. The plant was crazy root bound in the 10" azalea pot, and I couldn't even get into the soil to place fertilizer tabs, so I gave in and potted it up to a #10 squat polycan. Between all of the moving the water is a bit fouled, the leaves are a bit ragged, and my hands are full of pricks. I'll get pictures another day when all of us have recovered...
