From my experience it depends on the tropical.

I bring my tropical water lilies inside (Zone 7), so far I've had good luck
with Albert Greenburg, Evelyn Randig and Red Flare wintering well in
62-65F. Last year I tried Dauben, Tina and Wood's White Knight and they did
not come back. This year I put a heater in set at 70F, hoping the newest
one, Blue Capensis, would suvive. It was looking good till we lost power
and my little indoor pond dropped to 55*F. Albert, Evelyn & Red were not
fazed.

It is rather confusing.

According to the web site I am in zone 8-10, a lot of help. Probably
this year it would count as 10, my pond temp is 56 F. (rub it in?)

The books and web sites I have found discuss temperatures about 70 F
for growing conditions, what I hope to find is the survival
temperature, or maybe it is the same?
