I have Gloire de France in my garden and Lyn is right, give this rose 3 years without pruning, and you will have flowers like the photo. Gloire de France also enlarges by stolons which means the canes put out about 3 inches of horizontal roots and then these roots put up new canes. This is not the same as a sucker. My Gloire after 8 years is now 10 feet wide.
