your iris reminds me of 'eleanor roosevelt' but the standards are the wrong color. the beard isn't white in your photos, to my mind's eye. it's more lavender and yellow. (lol, but i have cataracts
) i don't know what your iris might be, but the form is more historic than modern.
is your iris an 'ib'? how tall is the flower stalk, from the base to the top of the flower?
