'Cutting Edge' is one I don't see discussed much. It's larger than the registration size and is a hosta with lots of "attitude". A few pictures from last August - Zone 5a. To give you an idea of size, in the 3rd picture it's bordered by 'Aristocrat', 'Gemini Moon', 'Alligator Shoes'. 'Undulata Univittata', and an unidentified Heuchera.
