I agree the height difference is sort of the "opposite" of the case jon was making. Sure if it were registered at 30 inches, and only grew to 12 inches, you might suspect poor soil, or some type damage to the plant, or the plant had not reached maturity, etc. Of course as is sometimes the case the registered height could be wrong. Am I correct in assuming most of the posters here have the plant growing around the 12 inch height and the exceptions seem to be the taller plants? I do not grow the variety.
