They seem to be quite different plants--can Russian sage be used for a spice, or tea, or as an aromatic enhancer? /
It can be used, similarly, to Sage. It is not related, and is not recommended for eating, but it is common practice to use them in teas.
Here is an article for more information on the plant:

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.

These plants I grew from a samll root and they grew beutifully, bloomed, cut back in winter and they came back every year. This summer they've bloomed but all their leaves are turning yellow.
Make sure they aren't being overwatered. If not, they may need some fertilizer or to be divided. Here are best growing tips:

Second year in berm. Good drainage, lots of sun until1pm no growth.patience?
You are at the very edge of where they can survive the cold. Zone 5. With this being said, you will notice that they will die back completely, or close to it, every year. This means that they will not have time to develop woody stems. You can still give it proper care to ensure that it looks its best.

I have 2 Russian sage plants that have pretty much taken over where I planted them, I would like to move them to a shadier spot in the morning but it gets afternoon sun, would this be a good move the plants are very unruly and the spot I have picked out is wide open and they would look great there any help would be appreciated
Russian sage prefers full sun, which is generally six or more hours of sun each day. I doubt if they would suffer since they'll get afternoon sun, but they may not thrive as well.

They were planted last spring in a rock retaining wall, 3' x 3'holes were dug and filled with soil, underground irrigation 2 litres 2x weekly and bloomed all last summer.
Likely, overwatering. These are pretty drought tolerant. They won't tolerate wet soils for long, though.
