are there any rules of thumb for this? any common ones which don't like being split?

so far, i've managed to split hostas and mint (walk before you can run...), but is this possible with plants like astilbe, dicentra, jacob's ladder, etc.?

There are only a few perennials that do not respond to spring division and they are…..Acanthus, Anemone, Aruncus, Centranthus, Dianthus, Gypsophola, Iris, Limonium, Linum, Meconopsis, Paeonia, Penstemon, Platycodon, and Verbascum. All other perennials are safe enough to divide during spring.
