Winterizing tropical water plants

Moments before taking that leap of faith into the pond Mike C
at was heard opining:

I have had luck with some tropicals that normally wouldn't survive by
putting them in the deepest part of my pond before winter. I am in
Zone 5 (Chicago) and use a heater to keep the water from freezing.
You'd be surprised how many tropicals/sub-tropicals can survive in the
30s. Freezing is what will kill most. With my cover and heater and
the ground as an insulator, the bottom of the pond is probably always
at least 38 degrees.
=====================
Which tropicals were you able to keep over this way? I don't buy
them anymore because I don't have room in my sunroom for any more
plants in the winter. Some tropicals get BIG. I'm in zone 6 central TN.

It's a little early to tell what made it this year. I know my Spider
Lily made it. It is not really a troppical, but it definitely is not
rated to survive a zone 5 winter. I am hoping my Taro comes back up
too.

*Note: There are TWO "Koi-Lo's" on this NG*

Is your spider lily white or red? I have the red one the woman called a red
swamp lily. It almost looks like an Amaryllis they sell at Christmas time.
I'm not sure what it is but she said it was tropical. I do bring both in
for the winter but they don't do well inside, getting spindly and pale. I
bring my Taro in as well and it always manages to have a spider-mite
infestation before Thanksgiving. These tropicals are barely worth the work
they take to keep them over......

Please let me know if your Taro comes back. I'd love to leave mine out this
coming winter.
