overwintering pond plants

[B Considine]

This summer Donna and I set up a largish pre-formed pond on our patio. Now that things are cooling down, I'd like to bring in the potted plants. I don't believe any of them can be converted to submersed growth. The plants are: Virgina Blue Bells (Ruella squarrosa), Lobelia fulgens "Queen Victoria" in small pots, and Water arum (Peltandra virginica) in a gallon pot. There's also some sort of lily (no tag) in a gallon pot.

For the first three, would it be sufficient to just keep their feet wet and place them in a sunny window? For the lily, remove the bulb and place it in a plastic bag somewhere dark?

Advice appreciated.

I overwinter my Crinum americana in a bucket in my fishroom, letting it soak up any extra light from the metal halide. It grows really leggy, but survives. This one is better suited for this since it has the energy stored in the bulb. An emersed setup would do well for what you'd doing.
