I had spider plants for years and never bothered dividing them. One plant and before you know it there are hundreds. I doubt there is any other plant quite so prolific.
OTOH, I do divide my peace lilies every so often. Out of four, the oldest is 30 years old. Putting them into progressively larger pots results in a look I don't personally care for. By dividing them they have been content in 20 or 24 inch pots for years. I've had friends tell me they can't keep them alive. I have actually found them to be quite forgiving. During the winter, when I forget to water, they tend to get a lot of brown leaves. When it warms up they go outside, all the brown leaves get pulled or cut until the plants look a little puny. Five months outside in the humidity makes them full and lush again.
