I agree with Pepper that the first photo is Campanula (commonly known as the bell flower).

I have reversed my opinion on the yellow flowers I have growing in my backyard. What I first thought to be Evening Primrose, I now believe to be Sundrop. Venturing out at dusk last night, I found the flowers had closed, whereas the Primrose purportedly opens at that time of day and closes in the morning. I also learned that the Primrose has a larger blossom and grows much taller than the Sundrop. Very similar in appearance but the Sundrop is a smaller plant. The photo posted above may well be that of an Evening Primrose, but what I have growing here is Sundrop. The test would be whether it opens or closes at dusk and how large the blossoms are.
