Hey, welcome to ATP, and to the Great Northwest. (I am from there, in FL now). We need a little more specific info about your location before anyone can really recommend plants for that bed. What part of WA are you in?
It's really different along the coast (zone 8, much warmer and a rainforest) than inland where there's lots of dry, high, cold winter areas. (zone 5? , very low rainfall).
