Name: Mary Lake Stevens, WA (Zone 8a) Near Seattle
Here are some easy things I found. You will find others that do well where you are. For example, the Bergenia-I turned up my nose at these, because they were common and I thought the leaves looked like cabbages. But then after repeated frustrating failures of other plants I bought some, both the common kinds and a new expensive cultivar. Every single one has survived. I really like them.
