Comments (5)Sammy, I think your right about my zone. I looked at the most recent hardiness zone map, and it puts me right on the borderline between 7-8, so I guess I would be zone 7b or maybe even 8a. The older maps put me in 7a. Global warming heating things up? It gets plenty cold and mucho winds, chill factor way down there in the winter. But then hotter than blue blazes in the summer, with the dry, baking winds. But really, we can grow pretty much anything, the Old Europeans get enough chill for a wonderful spring bloom, and the teas and chinas love the heat. Rosy will go into the primo spot, protected from cold winds and west sun. Jeri, it all your fault again for enabling yet another to the ARE Rosette Delizy. Can't wait to see the colors, but be assured I will be patient with her. Sherry, from reading your account, I am glad I do not have clay, the shape of your developing RD sounds like what I want. And I peeked back at prior RD thread and spied your fantastic photos, now I really can't wait to see her bloom in person!!! I knew she was a pretty rose, but yours is sublimely beautiful....See MoreRosette Delizy
Comments (14)I love Rossette Delizy and was thrilled when a freind of mine gave me his plant as it was slow to grow, which is typical of that class, but he was impatient. Several of my Tea roses had die-back when they were young plants, less than 3 feet tall, and I agree with Jeri, who has a theory that Tea rosebushes' immunity to disease appears to strengthen as they reach a mature size. "Die back" is caused by a fungus, named diplodia. I'd try spraying your "Rosette Delizzy"s leaves and canes with Cornell spray, which is too alkaline for fungi to thrive in it. Although I've not heard of such a treatment being used for diploidia, it seems logical to me that it might work, as Cornell is used against leaf fungal disease in roses. Plus it is a cheap substance, made of items that many persons have at hand. Diplodia can be easy to find, look for a discolored cane tip and cut into it, if the inside pith is not a healthy greenish white color, but instead a brown mushy hue, that is what diploidia appears like. After the cane has died it will turn black. I'd also feed such a rosebush with 10-10-10 to 15-15-15, depending on its size, 3 times a year to promote growth that has been lost due to disease. I would use the following strength of Cornell on the canes, and re-spray after rain or watering has washed it off. Cornell spray 1 quart water 2 teaspoons baking soda (this will leave a whitish residue, you can reduce it to 1 tsp. but it will not work as well) 1 teaspoon Canola oil. It must be Canola because that oil disperses in water and causes the spray to stick to the canes and leaves. The thing about diploidia die-back is that if you remove it early enough, it can do less harm, because it kills a cane from the tips on downwards. I'd try spraying the cut tips, with Cornell too so they don't get infected. Good luck, Luxrosa...See MoreRosette Delizy vs Archduke Charles
Comments (26)Malcolm, It's been a few years since I had AC. I do recall the flowers being a bit larger than OB, but otherwise so similar that I couldn't justify the room to grow both. And I admit to a fondness for OB simply because it was the first old rose I grew, not to mention its historical significance. My current OB plants were cuttings I rustled from an abandoned house in my neighborhood. Luckily I was able to take several cuttings before they bulldozed the house and the rose for rebuilding. I wanted to cry--that rose was huge. The base was like a tree trunk and it was a good 12 feet tall and around. Must've been there for years, pumping out the blooms despite neglect. Oddly, I've grown both OB and Cl. OB (which for me was always once blooming) and I found the flowers on Cl OB to more closely resemble the size of those on AC. Maybe it's because it bloomed in the spring when it was cooler, I can't say. It's odd that the climbing version is once-blooming, much like that of SDLM. I never had problems with balling on Cl SDLM, whereas the bush version balled badly in spring here. Still wouldn't be without her, though....See MoreRosette Delizy
Comments (10)I love this rose, even if it IS just 4 feet tall here, lol. She outdoes herself in the fall with even more vibrant color in the Fall than in the Spring. I doubt she'll ever reach 6' here (this is her fourth year), much less 10', but she makes up for it with exuberance: she's almost never without at least a smattering of bloom, and the beginning and end of the season are spectacular. And for some reason when I look at her I think, "THAT is a French rose". It recalls French silks, French hats, French romance. Did I mention I love this rose?...See MorePlumeria Girl (Florida ,9b)
