Hello; I am a complete novice to gardening, but I just bought a house last summer with lovely perennial plants all along the backyard borders. I live in central Iowa, and everything is starting to flower, but I have no idea what half of these plants are. Can anyone identify these for me please?

Any help would be much appreciated!
