If you watch the video that you took this screen shot from, she refers to it as water cabbage. I have no idea if she means water lettuce, but in any case if it's a floating plant it's probably not going to survive temps below freezing.
I vote Frog bit!
Now I want some! Frogbit (Limnobium spongia)
The green heart shaped leaves resemble a miniature waterlily and float on the waters surface. Frogbit forms buds that sink to the bottom of the pond to winter over until spring. This floating plant is well suited for container water gardens and smaller water features.
