I've moved Russian Sage a couple of times with no problems. A two year old plant shouldn't be too difficult, just take plenty of soil with it.

I also had no problems with moving, this is just the best plant, comes back every year, no deadheading, and blooms for over 2 months, the most beautiful blue ever!! I moved one in spring last year and it bloomed fine, a little shorter than the others, but it was still gorgeous and showed no signs of sulking at all. Have fun, and enjoy them!! I ordered some little spires, which are surpose to be dwarf russian sages this year, hope they are just as beautiful, it's my favorite plant, more like a shrub and a no brainer.

Perovskia is a shrub--often referred to as a sub-shrub. It transplants very easily, but always do it in spring. Usually dies if fall transplanted.

Thank you all for the help. The one I'm moving is the basic Russian Sage. I'll move it today, but should I give it more water than usual the first few weeks? I know they don't need much water, if any, under normal conditions.

I also have a 2 yr old Little Spire, but this one is an 'underperformer' for me. Perhaps because it is in partial sun.. I may move that one too :)
