Beautiful blooms, but grow really big (they need a 4 foot Pot!) vs waterlilies (which I have oodles of in my pond), They are also problematic in that they require 1-2 months of 80F before they even think about blooming, and they are also more prone to diseases then waterlilies are, and the chemicals needed to cure the disease will kill any Koi that are in the pond.
(hope you meant the plant and not some software game called Lotus Flower!)
