Potatoes on our side of the mountains require plenty of drainage if in containers but can still easily be done. We have such a kind and gentle climate so many things grow easily and well.
My yard is hotter and sunnier than the average Seattle yard, it's a good yard for roses but they are too fussy for me. I had a gorgeous repeat blooming scented climber that was aphid and black spot resistant, but the hubby really disliked it, and gone now is the picket fence with the roses and in it's place is that rockery that needs more dirt.
