The "aunt" of Bonica (MEIdomonac) if not potentially its diploid parent -- assuming the lineage disclosed for this reblooming f1 descendant from species(?!) is complete. The triploid "Swany" is a sister.

I planted this rose in the wrong place. It's huge for only a 2 year old plant (6 ft. wide) and will soon be competing for space with other roses. It should be moved or the poor thing will be pruned too much. (I'm probably too lazy to move it though.) This year it's laying on the ground mostly, but I can hardly wait for it to start mounding so the flower clusters will drape down in that beautiful way they do in photos. More than one source says it's self-cleaning . Just a few clusters on mine have been. A few others shake off easily, but most have to be deadheaded or they stick to the plant. That was a big disappointment. However, this rose has enough going for it that I'll keep it for now. Like the fragrance. Often I don't smell anything, but sometimes it's there - slight, but wonderfully fresh and sweet. It's also a very healthy rose bush (no mildew or blackspot so far), and as others have said, flowers well throughout the season.
