Quite nice, especially hand held at f/2 (although my EXIF states f/4). You must be solid as a rock.
I wonder if a slight vignette in image #1 might focus more attention on the flower...
So lovely; why the name, walking iris?
Beautiful flower Steven, IMHO your first image is the better of the two.
According to the response from Mr. Google --
So what makes this plant so unusual and how did it acquire its name? Well, because of its habit of propagating itself, the iris appears to “walk” throughout the garden as it fills the area with additional plantlets. When the new plantlet is formed at the tip of the flower stalk, it bends to the ground and takes root. This new plant then repeats the process. Thus, giving the illusion of walking or moving about as it spreads.
A beautiful flower, I really like #1
