Hi Kizhe

Thinking about the warmth factor and not really pond related but here goes.

We live in Zone 5-6. Gladiolas are a bulb that are supposed to be lifted in
the fall and replanted in the spring in our Zone. A number of years ago I
planted some within a foot of the basement foundation of the house. In the
fall I forgot and didn't dig them up. Next spring up they came and bloomed
well ahead of the normal bloom time. Every year we lived in that house they
grew and bloomed and I never dug them up. So....

If your sunroom has a basement and might leak some heat into the ground in
winter and your lotus are real close and you cover the pond with plywood and
something to insulate and maybe if you cross your fingers.... Well you get
the picture. Worth a try anyway. Good Luck!

Nedra, how do you overwinter lotus? From you webpages I gather you
just leave yours on the bottom. However, I think my USDA zone is 2,
and anything tropical has to be brought inside and put under
growlights or into dormant storage. I've kept a taro going for
several years now, and I'm thinking I'd like to try lotus.

Also, are there any that are good for complete shade? Pond #2 (under
planning) is going to be on the shady side of the sunroom.
