Heuchera, it should stay. They eventually push themselves up further and further out of the ground. I dig mine up every other year and rebury them more deeply, and I also divide any large clumps, to reinvigorate them.
It depends whether you like it or not They do push themselves up and out, but you just replant them deeper, as said. Very easy to propagate, but watch for vine weevils if they're in pots.
