I don't think anemones are immortal. At some point the "mother's" cellular structure will degrade to the point of being unable to repair itself. I stand to be corrected, but it is akin to plant propagation by cutting off a scion from a mature tree and then planting the scion to create a separate tree. The "mother" tree will eventually die as it goes through its life cycle and the scion tree will outlive its "mother" but it too will eventually die.
