Black Magic Hates Frost

The time has come to store the Black Magic plants for the winter. The first picture shows one of the Black Magic about a month ago with large healthy leaves. The second shows the same plant this week after several freezing nights - totally killed back. We removed them from the pond and put them in the greenhouse for the winter. This year, I am going to let them dry out over the winter instead of keeping them damp. It remains to be seen if this is a good process to over-winter the plants.
