Mariposa Autumn bloomed for me last fall after a late July order. I am in the same zone as you. It depends on the rebloomer too. Some only rebloom in warmer zones. Winterberry and Suttons list if it is able to bloom in our cold zone.
Leave a note, or email that you would love a gift Iris to be a plicata or rebloomer.
Your order looks just gorgeous. I would be very happy to see shots of the flowers when they bloom.
