Yes, if you see only Huey blooms, Abe and QE are goners, and you should dig out Huey, which is not a very good garden rose (blooms only once and gets diseases). The swelling where the canes diverge is the place where the scion (Abe or QE) is physically attached to the rootstock (Dr. Huey). There is no blending of varieties. If a rose is not fully cane-hardy in your climate, you have to protect the graft (aka bud union) from winter kill, or else only the hardy rootstock part survives. Plant your grafted roses so the top of the graft is a couple inches below grade. If there is no snow cover, push some extra mulch over the crown for the deepest part of winter only. What you like about Iceberg is its leafy, relaxed, shrubby quality compared to the sparse upright growth of hybrid teas and similar modern roses. There are lots of roses of that sort, though garden centers stock mostly hybrid teas. Many shrub roses are hardier than Mr. Lincoln, too. One of my favorites is 'Earth Song', a great bloomer and zone 5 hardy. Click "photos" tab at the link. Here is a link that might be useful: http://www.helpmefind.com/rose/pl.php?n=1695

'Heritage' will make a shapely 6' shrub if it is pruned to 4' and any rogue canes cut back to 3'. It cannot be kept as a 3-4' shrub. The yellow leaves with large brown patches are probably from cercospora rather than blackspot, but there may be some blackspot too. You are in one of the world's worst climates for blackspot where very few varieties will be clean without spray, and those that don't blackspot will get cercospora. Give 'Mother of Pearl' a try. It is hardy, BS resistant for me, and great for cutting. (Here we also have extreme BS pressure.)

It has a very mild generic-rose scent, so I don't think it could be anything with "Perfume" in the name. I'm checking Pink Peace on HMF. The house itself goes back to 1949, but it was remodeled extensively in the mid-sixties and I think it's more likely the roses date from then. Thanks, Sylvia

That being said, after saving them in two world wars, I'll keep my rock and roll LOL! Um ... you do know about Britain's "tiny little contribution" to music, don't you? ;-) Or do you need to be reminded of The Beatles, Led Zeppelin, David Bowie, Queen, The Who, Black Sabbath, The Cure, Motorhead, Coldplay, The Police, Duran Duran, Radiohead, Sex Pistols, Portishead, The Clash, Deep Purple, Pink Floyd, The Kinks ... (I'll stop now). :-D
