A few years ago when I started the pond, digging a big hole and piling the dirt up along with boulders to make a hill for a waterfall, I bought some pond plants and planted them in a couple muck buckets to wait till the real pond happened. This lily persisted and prevailed after all the others either quit or were eaten by something that pulled them out of the water a few years ago.
