Hi,
I live in Beausejour Manitoba Canada where we have very cold winters and unpredictable varying temps in summer. A 2B Zone.
This intermediate iris grows 12" high. Its prolific and hardy. Any guesses on it's name?
A search in the ATP data base with Size (SDB), color (purple /white), and form (plicata" will give you a starting point.....probably a dozen, or more listed for comparison....and , by the way !
Welcome Mveldman!! If you have any close-ups, especially of the beard then we can keep an eye out for it. You never know when one of us might run across a similar iris. Sorry I can't be of any help right now. Your garden looks lovely. Come back and visit us!
