Q.When Should My Russian Sage And Siberian Iris Appear?
I’m afraid they didn’t make through the winter. They were both covered over the winter here in Mpls. I put them in last spring.

Your Russian sage may not have made it through the winter because its hardiness (5) is right on the edge of your hardiness zone (4 to 5). The Siberian iris is hardy to zone 2 so it should have weathered the winter just fine. They do like moisture so be sure it didn't get too dry during the winter. It is probably a little early yet for it to break dormancy.
