There are a couple of ways to overwinter your water lily. The important elements is that they must remain dormant so you'll need to keep them in a cool location (50 degrees maximum), they must not be allowed to dry out and, their roots must not be allowed to freeze.

As long as you're successful overwintering bulbs, you should be successful with your hardy water lily. Just after the first frost, lift the container from the pond and leave the plant in the pot. Trim off all dead leaves and stems. Place the container in a plastic bag to retain moisture and store with your bulbs where the temperatures don't go above 50 degrees or below freezing. Check periodically to make sure that there is plenty of moisture in the bag. Maintain these conditions until spring.

Another way to overwinter these plants is to remove the rhizomes from the pots, prune all old leaves and stems, and store them in damp sphagnum moss placed in plastic bags. Store in an area that is cool (50 degrees) until spring.

Best wishes with your lily!
