wildflowers and some not so wild flowers

Here are some photos of flowers I have come across while hiking in Oregon and California. I was able to identify some through the help of the good old internet and my sister, however, some are stubborn and refuse to wear a label. They think they are too cool for a label. Any help identifying the unlabeled flowers would be appreciated.  

Skunk cabbage, Portland, Oregon.  (If you enlarge the photo and look at the bottom right of the flower you'll see a bee.)

California poppies, Sunol, California.

Daffodil, Portland, Oregon.

Trillium, Portland, Oregon.

Ice plant, Sunol, California.
