Radler of knockout fame has been breeding hardy, own root roses. I grow Carefree Celebration. It is one of the earliest to bloom and continues blooming all season. I still had blooms the day after Thanksgiving when my other roses were already hibernating. The blooms aren't as attractive or fragrant as hybrid teas or Austins, but the shrub is a blooming machine!!! The red and pink knockout roses were everywhere last year including the big box stores.
Speaking of big box stores, if you bring home a mini rose this spring try planting it in your garden once the danger of frost is past. Many are very hardy. Miniatures, in general, are quite hardy and typically grown on their own roots.
There are also some great Canadian roses including the Explorer Roses and the Parkland roses. I grow William Baffin and Jens Munk. I have seen pictures of Quadra, a very nice climbing red rose.
There are lots of other roses that grow well in our zone as long as you start with quality plants.
