What type of endemic wildflowers are these?

Question

I came across these pretty flowers while researching on a topic for my biology class and I wanted to do a paper on them but the problem is, I don't know what these are called so I have no idea how I should start my project. Can anybody help me out and possibly name these flowers for me. Any answer will be appreciated. Thanks!

Answer 1

3 looks like Lupine, #4 is definitely Columbine.

They might not be true wildflowers, though. The Columbine in particular looks like a garden variety that has escaped. True wild columbines have red in the flower, I believe.

Not sure on the other 2. But see if your library has a copy of Peterson Field Guide to Wildflowers. This great book is divided by color, then by major features of the plants. Very easy to ID plants from the drawings, in fact easier than by pictures. They also tell you which plants you might confuse them with, and whether they grow wild in your part of the country.  

Answer 2

1 looks like a Saxifrage (caespitosa?)

#2 is Silphium terebinthinaceum (Common Name: Prairie Dock) and is known as one of the wild sunflowers.

#3 is probably Large-Leaved Lupine (Lupinus polyphylllus)

#4 is most likely a cultured Columbine. The common wild Columbine is red/orange and yellow as the first answer suggests and a yellow and white varitey is also found in some areas.
