As my pond plants begin to fade for the winter months, my pond is becoming barren. Does anyone have suggestions for aquatic plants that will continue to perform through to spring? Horsetail, sweet flag, miniature rush and papyrus still look OK. Floating plants just hanging on while cannas, water lilies are in decline. I'm also worried about the taros. Mild frosts to low 30's at night at the coldest part of winter in Los Angeles area.
