OK.
Everyone is so convinced it's a lily.
It's in the far back Southwest corner of my property and the other lilies are in the East side, not 10' from the property line on that side.
racking my brain, the only thing I can think of is that I got some kind of lily in trade that wanted shade. I know at one time I had a rain lily I got in trade, but they have different leaves.
ARE THERE any lilies that want shade?????
