I only have Tamora and Scepter on that list but I got both of those b/c of Harry. I love Scepter'd Isle, it may be my favorite of the whole season and it has almost continuous bloom. Especially notable since this is Year 1. I can't speak to fragrance, I have a poor nose but I love love love the rose.

Harry's photo of Tamora and Scepter together is why I want both of them. I don't have a good nose either, so fragrance is not a big deal for me. Thanks

To my nose Sharifa Asma is one of the better Austins for scent, and it also has a decent shrub form. Scepter'd Isle is pretty but it grows in octopus form, at least here in my part of California. I think it would do better trained as a moderate sized climber. I forget the fragrance, since I got rid of mine several years ago.

Rosefolly

I think Sharifa also has very delicate and elegant flowers. The color is interesting too, shades of pink and a little yellow, not flat at all... I don't grow the others you are thinking about, so can't compare. My Sharifa is next to Geoff Hamilton, and I love them both, but Sharifa is the one that stands out.

I have all three. Remember, JC just came out only a year or two ago so it's impossible to talk about long term characteristics.

Sharifa - the best scent of the three. Beautiful blooms, but not very many of them, even in the flush, at least for me.

Here's Sharifa: http://www.pbase.com/tivoli/image/39312178

I do have some Sharifa's in this link, which shows a good flush, and other images, but I don't think that flush is typical, I think it was a lucky year.

Scepter'd Isle - a myrrh scent, quite nice. A crazy number of blooms during the flush and decent after that. A beautiful, sort of caged framework of canes that are almost always self supporting except maybe from a bad, windy storm and then they prop back up again. I wish I had the time to get an image of the bush, I can't right now. Well, here's two, the bush shot one is the one on the right. Gruss an Achen is the one on the left. Not a great picture, but it gives you some sense. The other image is just a bunch of buds and some new flowers, but look at all the buds and I have more of that type of image with a zillion buds.

Jubilee Celebration - I really do love this bloom. It's beautiful and has beautiful, rich color. I don't think it has a strong fragrance. Can't say much else about it, it's too new.

Here is a link that might be useful: Scepter'd Isle

All three of those are winners here. You may have to spray for blackspot.

Jubilee Celebration is wonderful, so far 2 years it is a pretty petite grower @ 3'. Mine has an Abraham Darby type of fragrance this year. The first year it had very little. Scepter'd Isle is rather large and octopus-like here with not a lot of fragrance. Sharifa is more upright in habit and very fragrant. Another one to look at is 'Bishop's Castle', which is a fairly run-of-the-mill medium pink, but with rapid rebloom and a wonderful fragrance--old rose mixed with a touch of vanilla extract. Yummy.
