I'm in Victory's hometown (Downingtown), planted 3 cascade/3 willamette from freshops last saturday (so 10 days ago)...they had been in the fridge for 4 days prior to planting. No root hormone or anything fancy, just letting them warm to room temp. overnight before planting, then doing the 12" holes with wood ash at the base, and a mix of horse manure & tilled dirt + mulch in a mound with each rhizome just over 1" under the surface.
As of yesterday, 2 of the willamette sprouted through (just in time for this morning's frost!) and one of the cascade. I'd say be patient and if you're really curious, dig down CAREFULLY near the rhizome to see if growth is occuring.
