Advice On Moving Outdoor Plants From Alaska To Colorado?

I am selling my house and eventually moving into another house. I would like to take some of my outside plants with me. However, I will probably live in an apartment for about 6 months to a year before I find another house. Can I plant a Peonia into a pot and keep it indoors until I can return to a more permanent outside garden? Also, what about a Bleeding heart?

I tried to winter a Bleeding Heart last year, by putting it in a semi-dark, cool room and sprinkling it lightly with water every now and then, but it didn't make it. One more question: I may move from Alaska(zone 5-6) to Colorado(zone 4-7), Can you take a piece of the root of the above mentioned plants and still have success re-growing? How.
