Hey, I'm just refreshing this post to see if I can get an answer. Thanks so much,

Hi, Mikayla (love the name, same as my daughter's),
The dumb answer to your question is that yes, it can be grown with winter protection...but the question is how much protection Ballerina will need to perform the way you would like it to. We've all heard of rosarians who perform herculean feats each fall to protect their tender roses - - tipping and burying them under feet of soil, for example. I assume you're planning on own root roses?

Other questions are where do you garden and will you be satisfied with Ballerina as a shrub? Do you have snow cover? Is the winter cold nice and consistently cold, without freakish repeated thaw-freeze-thaw cycles?

If you cannot find a local rose society with a list of hardy roses, my next suggestion is to find a good cold zone rose nursery specializing in hardy roses to check if Ballerina is on its list. I usually check Sam Kadem Roses in Minnesota, for example, or Great Lakes Roses in Michigan (only Zone 5). Great Lakes lists Ballerina as hardy in Zone 5 without protection. I know that's no guarantee of survival in Zone 4, but it's a start. I also check the Canadian Rose Society list of recommended roses. This produces inconsistent results for Ballerina because it isn't on either the Canadian or Sam Kadem lists.

Let's hope someone who knows the answer to your question will post.
