Continuous bloom is a bit of a misnomer when it comes to roses. They typically bloom in flushes and some repeat faster than others and the maturity of the rose usually plays a part as well. Based on your height requirements and other wish list, I'd really take a look at getting Roberta Bondar. It is not intensely fragrant, but does have a good fragrance to it. The blooms are a very large clear yellow that hold well in the heat. Disease resistance is above average as well and it will stay in the 6-8' range you are looking for. The best of the lot is probably Golden Gate, but it wants to be bigger than 6-7' tall and will require some regular pruning once it is mature to keep it that size. Normally a 8 to 12" climber.

Austin's Mayflower (pink) is very disease-resistant and blooms a lot. I'd rate the fragrance moderate but nice. The Buck rose Earth Song is a rich medium pink and disease-resistant and strongly fragrant. It is a grandiflora but grows more like a shrub. Don't know what either one would think about 4-5 hours only of sun, however--but that could be a problem with a lot of roses. Hope that helps. Kate

I enjoyed reading, but saw only mention of climate causing difference in disease-resistance. Actually a much more important problem is that there are so many different strains geographically, that BS resistance in one location can mean absolutely nothing in another. This is why the Vigorosa roses are reliably blackspot resistant--the breeding program includes testing with a variety of BS strains. It would be really helpful to organize this discussion by states, etc. Secondly, I am wondering how many have heard that organic gardening techniques actually do more for roses in resisting disease than spraying in many cases. In a truly organic bed (no chemical fertilizers or pest & disease sprays) the soil organisms that thrive and multiply tend to push out or decrease the populations of pest fungi & bacteria. I sure hope this works for me as I have just bought a new home and am in the process of preparing a large rose garden.

I know this is an old thread but its been very good and useful so I thought I'd chime in. All the roses i recommend have been mentioned here but I live very close to you in Zone 10 Florida so I thought I'd let you know what has worked in my garden. I have over 50 roses and my best performer is by far Belinda's Dream (you probably have it by now, if not, get it!). Always in bloom all year round, doesn't mind heat/humidity or rain has perfectly formed blooms AND its fragrant. It has it all! One of my other good performers so far have been some Ausitns. My BEST bloomer is Huntington rose, but it does get black spot a bit. I don't spray her so i just prune her a bit after every other flush and she keeps bouncing back. Queen of Sweden has been excellent. Not as big a bloomer as Huntington but NO black spot at all. She does grow TALL though (huntington grows WIDE), So Far she has stayed very narrow and tall. Jubilee celebration has done well but she is too new to tell if she'll get through the rainy season without too much BS. Wollerton Old Hall, great fragrance great BS resistance but bloom color is not my cup of tea (kind of a tan/beige). Alnwick rose has done well too as well as Abraham Darby (tried and true). All my Austins are in planters though, none in the ground. As for HT roses my best performers have been Mr. Lincoln, Olympiad (very good), Gold Medal (also very good), Queen Elizabeth (kind of gangly but blooms alot), iceberg and brilliant pink iceberg are great but grow wide, not tall (they stay short though). Pretty much all my HT get some black spot in the rainy season but i just trim them come fall and they do well all the way until the following May. If you are looking for a more bushy rose try the new KORDES varieties. I have had ABSOLUTELY no black spot on Lion's Fairy Tale and Mandarin Ice, and I hear all the Fairy Tales are just as good as lions. I'm getting a few more this year from that series. OH also don't forget BUCKS roses. Superb! I have Polonaise and Golden Princess and both are great with BS (very very little) but by far the best one has been Quietness! She has NO BS and beautiful fragrant blooms. Very Fragrant! Some roses to stay away from would be Oklahoma, Double delight (every one raves about her but she's a BS magnet in my garden) Angle Face (same). Cherish (love her blooms but same BS issues). I grow most of my roses in planters so you may need to see if you can find any of these on Fortuniana RS. I highly recommend the Kordes ones though, they have really thrived own root with NO disease they stand out like champs. They almost don't even look like rose bushes they are so leafy. Duchess du Brabant has been another good one. She does get a little BS but she seems to shake it off quickly. I just also got Rosette DeLizzy and clotilde soupert but they are still babies so too soon to tell. Good luck and let me know what does well in your garden!
