Our garden is in a suburb of Mpls. I planted two on a East facing hill side two years ago. The first winter, a plant halfway down the hillside died but the one farther up the hillside survived. There is more snow cover this year and so far, the winter has not been as cold.
I think this is a stunning plant in a shady area. Hopefully, it will make it this year.

This pretty carex can be agressive. I made the mistake of letting it loose in a partly shaded bed with even moisture and good soil. It promply took over and started choking out everything. Digging it up was quite a chore. Planting it in dry shade seems to keep it in bounds. On the plus side, deer have never bothered it in my woodland garden, and they have eaten almost everything else I grow at one time or another.
I've had it for 3 seasons. It's not aggressive where it is, a full shade dry spot on a north facing slope. The other plant was in a half-shade on an east facing slope and it did not show much progress so far. This season I had babies that went 2-3" from the mother plant. The runners are rather think. It seems that long cold winters and lack of water keep it under control for me so far.
What I like about this plant in my zone so far is that it lasts well into the winter when most of the other plants are gone dormant.

Carex 'Ice Dance' is beautiful and It lights up a shady spot very well. However it's very INVASIVE and should be used with caution. Other similar Carex are available that are clumpers and similar in appearance which don't have the same problem. Ice Dance sends tough runners out to start colonies and these can replicate quickly. A good plant for the shade where nothing else will grow/or you don't mind it taking over.
