Using houseplants in the pond

This pond is totally enclosed in a courtyard, creating a microclimate warm enough to use houseplants that like wet feet.
You can use spaths or pothos, in or out of the water. I have even potted up color and put them on a stack of concrete blocks (painted black) or upside down flower pots, so their feet were not in the water, but the pot was just barely on top of the water.
