A lady gave me some irises she said were given to her as wild irises. She had mentioned before that
she had a source for the old blue flag irises. The leaves have vertical ribs and the rhizomes are about
the size of my little finger and have nice healthy white roots and a lot of black, hairy roots. Don't want
to take a lot of time from the other threads but can someone give me a rough identification of species.
