This is not the best time of year to be pruning roses in your zone. Heavy pruning should be done in the early spring (March) in cold zones. Michael and Karl are probably correct about the root stocks. But the first thing you need to do is cut out, to the base, all the dead wood and weed so you can see what you actually have. And cutting out dead wood can be done anytime of year. If you do that much now you'll at least be set up for a hard prune in the spring. Your idea of tying up the canes to wires on the wall is a good one. You can do that now too and it will help next spring. Then in the spring you can do what Michael suggests and cut out about 1/3 of the oldest, woodiest canes. It's OK to cut out more if it's still too large to control but I wouldn't cut them all off. Leave at least 1/3 of the newest canes alone. You can cut them shorter if necessary but not off completely. Once you have the climber tied up you should be able to see the other roses that are underneath. Again, cut out all the dead wood now. Look over the remaining canes carefully. Any canes that look damaged or diseased should be cut out. Leave the rest alone for now. In the spring you can prune them better for shape and size when you see what comes back. When they bloom next spring take pictures of the buds, partially open blooms and fully open blooms along with pictures of the full plants, new growth tips and fully grown leaves. These are the kinds of pictures needed to identify your roses. If they are root stocks you'll be able to decide then if you want to keep them or dig them up and replace them with better varieties.

I can tell you that any of the Benardella roses (Show Stopper and Power Point) are bred specifically for exhibition form, are not stingy, and are at least hardy to my borderline zone 7a/6b area. I would expect that they are hardy throu zone 6, but I can't guarantee.

I'm sorry if I misunderstood your earlier post. This one may not directly connect with your posts either, but it is information that bears directly on registered names. There are two different things often referred to as "registered". They are quite different and can lead to confusion if not carefully defined. The registration to which I was referring was registering a rose with the International Cultivar Registration Authority - Rosa, which is the American Rose Society. This registration puts the rose in the historical record for roses internationally. It also makes sure no other rose can be registered using the same name. However, it has no control over sales names. Roses are often registered using their code name, or varietal denomination, and their sales names are just listed as synonyms. Thus Veterans' Honor (aka City of Newcastle Bicentennary, Five Roses Rose, and Lady in Red) is registered as Jacopper. The second registration is acquiring a registered trademark for the name. This is the source of the î symbol following names. This comes from the government and supposedly insures that no one else can sell a different rose using the registered trademark name. However, it does not keep the company that trademarked the name from using it for more than one rose. Poulsen, Kordes and others spend a fair amount of time and money registering names with the European trademark authority, and they feel they need to use them often to get the benefit from it. Thus they both do sell more than one rose using the same trademarked name at the same time. I am not aware of any cases where they used more than one trademarked name for the same rose, although I suppose it is possible. Adding confusion to the situation, some companies also trademark the collection names. Thus you could have a rose with a trademarked name being sold in a collection that also has a trademarked name. They could sell the same rose with the trademarked name in more than one collection with a trademarked collection name, or they could sell two roses using the same trademarked name - one in each collection. But no one else can use any of these trademarked names. Finally, the rules say if you register a rose with the ICRA-R, you cannot trademark that registered name. Or if you trademark a name with the government, you cannot use that name to register the rose with the ICRA-R. Life would certainly be easier for all of us if each hybridizer would only use each name once, and no one would try to use a name someone else already used. However, that isn't the world we live in.

They had several this year. Here's one, Beach Blanket -- or else look around on their wholesale site, which is still up from last season -- link below. Here is a link that might be useful: J&P wholesale site
