Normal growth on roses, or something else?
Hello!
I've been noticing some odd-looking growth on a few roses; the first two are of Earth Angel, last couple are from Princess Alexandra. The bushes are about 30 ft away from each other. Bright pink thorns have been around since March on PA, and I'm just begnning to notice some distortion in the leaves. Normal, or early signs of something else? Very grateful for your input!

Moss Rose or something else?
Comments (24)I was just thinking "what about the Ralph Moore mossed minis?" as possibilities for a "moss rose" getting to the Philippines when I opened this thread, but I see someone beat me to it. What's the difference between a Modern and OGR Moss? Well, the first Moss roses were sports on Centifolias, then on an Autumn Damask. Soon after, the moss-trait was bred into Portlands and some Hybrid Perpetuals, resulting in the repeat-blooming Moss OGRs. Mossing is just a trait (hardly enough of a characteristic for an entire class), and among the Moss OGRs, there are differences within the group resulting from the moss trait being bred into other OGRs. Some are clearly Centifolias-with-moss, others might be Portlands-with-moss or Hybrid Perpetuals-with-moss. But if you erase the moss, the plants are still clearly OGRs. Fast-forward to the 20th Century, and Ralph Moore's mini roses started being bred with the OGR Mosses. In doing so, he transferred the moss-trait into modern mini roses, and continued breeding to more modern mini roses to dilute the OGR influence. When you see one of his Mini-Mosses today, the plant will clearly be a modern-type rose, but with the moss characteristic. Thus, while "Moss Roses" are an OGR class, they really originally refer only to the mossy Centifolias, Damasks, and Portland-like roses. These are OGR plants with the moss characteristic. But if you have a modern rose with the moss characteristic, it's not an OGR Moss. In all honesty, I'd actually prefer the class was just eliminated, being as it's built upon one characteristic which can appear in (potentially) any other class. What if someone today bred mossed Hybrid Teas? How would those plants look when lumped together with 'William Lobb' into the same class? It'd be more accurate to put the Centifolia-mosses into the Centifolia class, and simply list all the Centifolias as either "mossed" or "un-mossed". Same for the repeat-blooming OGR mosses -- put them into either the Portland or Hybrid Perpetual classes, whichever fits them better, and have "mossed" or "un-mossed" Portlands and Hybrid Perpetuals. And for the modern Mosses, stick them into an appropriate category as you would if the plant was unmossed. But that's just me..... :-) ~Christopher...See MoreShould you NOT give your roses an aspirin at normal growth condit
Comments (2)Found the past article about aspirin & roses---it was in the "Heritage Roses" Aug 2004 newsletter. Told about a Corrine Clifton article in the Southwestern Oregon RS newsletter using a dilute aspirin spray that temporarily stopped downy mildew. Treatment was at 10 day intervals while the temp was around 60-65F. Used 3-325 mg aspirin tablets per 4 gal water plus a TBSP of soap as fixitive. She noted that the aspirin sprayed roses had larger new leaves, bigger canes & more blooms. So some anecdotal stuff on roses & aspirin but it would be interesting to have a scientific study with controls to see if it is worth the effort & time to apply aspirin....See MoreRose rosette or mildew or something else . . .?
Comments (18)Okay. I hit the garden center early this morning and bought my horticultural oil, mixed up a concoction and sprayed down the affected rose bed. It made the powdery mildew temporarily disappear. Which oddly made the red parts more worrisome. I pruned out the worst. Here are some close up shots. Interestingly, there are almost no thorns on these witch broom areas: My neighbor across the street has a front bed of knockouts. I have six more peach drifts in a sunnier bed about 30 yards away. Can I afford to watch this bed and see what happens after I spray?...See MoreDesert Rose branches bending with growth. Normal?
Comments (5)Allan, This can be usual growth expected from many Adeniums. Even in climates where they have long growing periods and warmth most of the year. Factors that could lead to this outside of above conditions could be not enough sunlight, too much nitrogen in fertilizer. The majority of people would prune this plant in order to keep it with a more compact growth habit and usually a full head of blooms. More blooms as there are more branches which form from pruning, which gives more terminal growth for blooms. Rick...See MoreSamuellaZ6a

3 years agolast modified: 3 years agoI thought the same as what mad_gallicasaid- that it could be Rose Rosette Disease-BUT only if they are getting distorted & knarly & weird looking, because this time of year fresh new leaf growth on some roses look rosy also.
Most of your photos look ok to me from what I can see. I wouldn't cut it off until I saw sure signs, and then I'd cut it off and bag it and wash my clippers really well, because I heard it's caused by a virus.
Also I see you are zone 6a and I'm in zone 6b and a couple of those really cold nights recently seemed to be harsh on my New Dawn Climbing Rose, so a mild frost bite maybe?
Right now all of my Rose Munstead Wood have really pretty red leaves and it's not that disease. I've seen Rose Rosette Disease attack roses at a neighbors house and it is distinctly odd looking in texture and form, and really looks "wrong".,and yes it's red but not healthy looking growth.There is a good photo on this link:
"Virus transmission occurs most readily between the months of May through mid-July when plants are making active growth. Symptoms from new infections usually start appearing in mid-July. In general, smaller plants go through the disease stages more quickly than larger plants. source-http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/viruses/rose-rosette.aspx
