These are bearded iris with one Siberian iris.
The third is more fragrant in my opinion but I can't decide the more beautiful. I only know the name of the first one, 'Speeding Again'. The rest have been given names as to who and where they came from. For example, the Siberian iris is called Danielle's iris, the yellow is Carrie's, the yellow/purple is Danielle's, the blue is Digby blue and so on. The name is not as important as who and where it came from. It's special knowing it came from a friend and even more special waiting for the gift to bloom, like Danielle's Speeding Again.
