I grow Liebzauber. Or at least I did--I think its dead now. Here's my Leibzauber saga. I got it from Pickering for Fall delivery along with Olympiad and Royal William. The roses were mounded up for winter but when I uncovered them in the Spring, Olympiad was dead with canker Leibzauber had died back to the bud union from canker, and Royal William was fine. I spotted a bud emerging from the bud union on Liebzauber so I kept it and planted it in back where it didn't matter whether it lived or died. It grew slowly over several years as a one cane wonder but finally after about 5 years it built up to a vigorous, bushy rose. Last year, when it was 6 or 7 years old, it came into it's own and produced the most enormous roses I have ever seen. But this winter it got down to 15 degrees. Leibzauber is black all the way to the ground. I don't winter protect it (see the canker problem above). So I think I will be shovel pruning it. Bottom line--I would be concerned that it is too tender for zone 4 and it's suceptibility to canker might make winter protection a problem. Royal William is a reliable,vigorous and healthy rose. The blooms are bluer than I would like. I can't vouch for fragrance--none of my roses in that bed are fragrant and I don't know why. Some comments on your other selections--Chrysler Imperial has the best color of any of my red roses and is the standard by which I judge them. The color is rich and velvety with no bluing. But it is very prone to blackspot. It does respond to spraying though. Overall the bush is very coarse I am trying to find a red rose that has the color of Chrysler Imperial with flowers with good form, on a good looking, disease free bush. Haven't found the ultimate red rose yet. Rouge Royale was shovel pruned after a couple of years. It had a bad tendency for bullheading and vegetative centers in the first flush so it wouldn't be until late July before I would get a decent rose off of it. Ingrid Bergman is supposed to be a great rose. I wouldn't rule it out. By the way, Konrad Henkel is a reliable red. I have won Queen of Show with it.

I am not sure that I have a picture of full bush. The one below is a fraction of bush approx 1/4 of what is above the fence after spring prunning. It is a monster bush, right now probably 10 feet high and 6+ feet wide. Very strong bushy upright grower for me. Right now I have to leave my house to go to work. I can try to make a picture in the evening if I return before it is dark outside. It does repeat, but not from year one and nothing comparable to spring flush. Another piece These was taken when it was just two year old baby. Olga

My experience with 'Rugleda' was one of suprised delight, then disappointment. It combined the best features of Kordes roses (glossy leaves, vigor, brilliant blooms) with typical rugosa traits. Only drawback was the utter lack of scent, another Kordes feature. But after several years mine simply died after one of the mildest winters on record. It had been though much worse winters and it came through those just fine. 'Rugelda' sort of checked out.

Iris - I think Liebeszauber is a very good rose. I have two of them and they both repeat quickly, with good bloom production and the blooms nearly always have a nice shape. Each bush is nearly 8 ft. tall, which is different for me, I've never had a hybrid tea that tall, but I love the blooms enough, I don't really mind. Sometimes mine are very fragrant, but not always.
