EDIT: I suspect if you leave them in the containers, they will behave themselves and stay small for a year or three at least. I've never tried it. My thought is, if left in the container, they will get root bound eventually or send roots over the top of the container to the pond bottom and spread from there.

Maybe Bill C will see this post and chime in. He is the expert on lilies.
