What's the natural growth habit of a never dug dahlia?

I overwintered several dahlia clumps successfully and they are growing like mad and sending up multiple healthy shoots even though my region still hasn't quite reached our last frost date (usually around May 15) yet. Looking at the current forecast we may even get a dahlia damaging frost this coming Monday night. Anyway what I'm really wondering about is what is a dahlia's natural growth habit if it is left permanently in the ground in a climate where it can survive every winter? Does the clump keep getting ever larger and larger making oodles of tubers? And does it then send up zillions of sprouts as the clump gets larger and larger? Or is there a point at which it becomes self limiting?
