Don't think so. They get too big, but they do grow nicely submersed when they are little. I had a tiny seedling come up back in August, and it looked nice for about two weeks with light green leaves that spiraled a bit. It quickly got up to the surface, and started poking its leaves against the top glass. It soon became apparent what it was. Cattails produce huge quantities of tiny seeds that float away on fluffly down, and they rain down indiscriminately everywhere. Apparently the soil that I collected for that tray had a seed in it. I was impressed by how rapidly it grew submersed. It would make a nice aquarium plant if only it stayed smaller and submersed.
