That's it, gorgeous.

It survives winter, but does it die back to the water when frost or
freezes occur?

It dies back.... and seems to have a hard time coming back if left
submerged. It is currently growing well in a couple of the blocks that
surround the lily pond. I'm thinking of digging in the pots I currently
have in water instead of leaving them in the pond, see what happens.
