I planted a boatload of Immortality iris two years ago and they are in bloom right now. They look good with Europeana, don't you think? Another re-bloomer that I have been enjoying in early fall is Blue Suede Shoes.
Sorry to hear about Rainbow Sorbet. I depend on mine to carry my garden through the thin part of summer. I wish I understood more about why roses do not bloom (too much shade, not enough water, too much nitrogen, not enough phosphorous, other stresses such as heat or cold or gophers nibbling on their roots). Did it bloom well for you last year? Maybe it wants some Mills Magic for Christmas?
