The second one is just an old dying leaf. Chances are it's from the bottom or interior of the plant; otherwise there may have been some injury to the leaf stem. I pulled off some of those this morning just because I don't like looking at them. Everyone probably has leaves like this every year. Experienced growers don't notice them because they know the death of an old interior leaf is not a problem. Some varieties and classes of rose produce more of these mottled, dying leaves than others. I don't recall seeing them on hybrid teas much if any. If the first one is just one leaf, I wouldn't worry about it. Various accidents can befall individual leaves, including malfunction of interior systems. If more like that develop, take a sample to the ag extension office. The fact that the midrib stays green indicates that it is not a disease, possibly a severe deficiency symptom, or burn from the excess of something, such as ammonium nitrogen. Again, this might result from a malfunction of that particular leaf.

i gave up on roses a long time ago .. 100 hybrid T's .. because of the chemical regimen needed for perfect plants ... like 4 to 5 sprayings over the course of the season ... of a multitude of products ... but jean is correct.. if you just a have a bush or two.. its a LITTLE COSMETIC DAMAGE.. and not worth the effort ... be amazed by the show.. rather than horrified with it ken

flowerlilies, Often people who work in garden centers don't really understand much about pests, diseases, and chemicals. You should ask first on the GW forum for the particular kind of plant. And don't believe the first poster who responds, because we can make mistakes too. Though, if we let a reply stand without further comments, that's probably a tacit approval. It's really important not to panic and apply a barrage of remedies before you have a good diagnosis. Also, when you post a question, it's important to give a general idea of where you live, because pests and diseases are regional, rainfall and winter damage can play a role, etc. For example, a diagnosis of scale insects on roses would be more likely if you are in Southern California, Hawaii, or Miami. But rose midge, suggested above, doesn't exist in those places. One thing I can say for certain, the purple spots with lighter centers are either cercospora spot or spot anthracnose, both fungal diseases that usually don't require control measures. Also, there may well be some spray damage, because homemade and "organic" sprays are rather likely to damage plants if not used carefully. Large purple smears are often the result of spray damage. What are you saying is wrong with the open mauve flower? If the grayish things are scale, they will scrape off easily with a fingernail.

I wondered if it might be Super Bonica, but that still doesn't seem to grow nearly as big as your rose. Try the regular 'Roses' Forum here; they get much more traffic, and they should be able to ID it for you, if anyone can. It's a gorgeous rose - I'd love to know what it is too!
