Zuzu!! I'm going to be forever stuck with the image of someone pouring ice on their plants to trick them into thinking their in winter
and since your "signature" says "unrepentant smokers unite" my image is of you with a cigarette hanging out of your mouth while dumping the ice
I'm in stiches! Seriously though your yard sounds totally lovely! I want to see photos!
Cheers and welcome to the PNW! in spirit!
