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!

Prairie Harvest is a nice yellow that will die back to the ground and come back vigorously for me every year. No disease, but the thrips love it. In the sun, it will fade to a chalky whitish light yellow. There is a new yellow knockout this year, but I don't know much about it. No, I'm not talking about Carefree Sunshine. Molineau is a nice yellow that nicely survives my Chicago winter with protection. A good bloomer, with nice fragrance Topaz Jewel gets BS and is not as hardy as other Rugosas, but survives in my garden with no protection. Last year, I had to cut it almost to the ground, though. TJ grows at akward angles, so is best to grow in a closely planted group. Perdita is pink in my garden. Not at all yellow for me. RU sells a yellow sport of Tamora called Lovely Child that has worked well in my garden. Here's a pic Julia Child is floppy. Strike it Rich isn't really yellow. Think Cantalope. I grew it this year and really like it. Not much fragrance though. I have grown Livin Easy and like it a lot, so Easy Going should be a good one. Lemon Spice is my favorite Yellow. I protect it and spray it, so it probably doesn't fit your criteria. But, if you want a non stop bloom machine for cutting and sniffing, Lemon Spice is the answer. Gets kind of tall and lanky. Jude the Obscure is winter hardy for me with minimal protection, but not really yellow. Apricot. Great smeller, though. The only yellow that I have that is disease resistant w/o spraying is Prairie Harvest. Al

I am glad to see this thread updated. I think cupshaped--I do wish she and Jim from West NY were still posting here--made a very good point about fungi developing resistance to fungicides, In view of the recent news about "superbugs" and "superweeds" having evolved resistance to herbicides and Bt engineered corn, I think her point is one we American gardeners ought to be taking seriously. I am growing and trying to preserve some of the older Tantau floribundas. They do BS, but leaves grow back quickly when I cut off the spotted ones, and do seem to be hardy with protection. The colors are like nothing else I have seen among roses. Paul Zimmerman has said in writings and videos that roses will often develop some resistance, as individual plants, to the diseases that might be present in one's own area.

MN is very black spot resistant in my garden too. If any rose is gonna get it, they will get it here lol. Most summers have been really steamy and rainy most every day. This summer is a little drier but MN did great last summer when it rained about every day and into the 90'sF. MN really likes full sun here. I still have him in a pot but its probably about 5ft or so now, I haven't really looked lately. He is growing into a Blue Girl rose who thinks she's a climber. I need to separate him out and re-pot into a larger pot or get him into the ground soon. He is own root. He kinda languished last year but this spring I put him in full sun and he went a little crazy with lots of new growth.
