the flower in pictures 4 & 5 is Ratibida pinnata I believe. http://www.illinoiswildflowers.info/prairie/plantx/yl_coneflowerx.htm It helps to put where you found the flowers.
dont think that's it, but thank you for trying. besides this genus is not in my country's database (http://hirc.botanic.hr/fcd/) [not even in European flora, I believe]. but thanks... at least someone tried:)
DYC's are almost always difficult so give it a second look and see if you agree. http://davesgarden.com/guides/pf/showimage/42554/
hm, you were right to suggest a second look... I didnt look up a synonym for Ratibida. Here we use Rudbeckia, and it turns out to be Rudbeckia laciniata. any ideas on the rest? Last two, could it be Silene italica or Silene nutans?
