I think I agree with Jackie, Stan. This picture looks very much like one of TS's variations to me. I also think the striped one could be just another variation of TS caused by any number of variables in the weather. Or it could be a sport! I've had a few odd ball blooms show up this year on my roses. It was a crazy winter, many of the roses were severely damaged and had to be pruned to nothing, even the summer has been unusual, all of which could be causing these mutations to show up in blooms.

Thank you all for the input. Thanks so much Jackie and Seil. I am glad the rosebush still had the tag on it buried under the gravel mulch. Last year I don't remember her having blooms with the pronounced stripes but it has been a weird weather year. And it could be that one side of this old bush has actually form a Sport. Thanks again soooo much! :)

Rust and mildew are entirely different matters. Baby Love has extreme vertical resistance to some black spot strains. But once they mutate and figure out how to "pick the lock", it collapses and frequently dies. As long as it remains resistant, it's remarkable. That strong vertical resistance is what is hoped to be bred into further roses, combined with as great a horizontal resistance as possible.
Vertical resistance relies upon one gene for protection. Horizontal resistance depends upon multiple genes. Each type can provide protection against one, or numerous strains and both can be combined in a single seedling. Finding which are present in the parents; selecting the best parents to mate; then selecting the seedlings with the greatest combination of the resistance types are the issues. Hopefully, as money becomes available, invitro testing will become possible and affordable so these questions can be answered. Kim

You're welcome! Oh, yeah! Roses change DRAMATICALLY with climate and season. I've seen roses I've grown for years in other climates and asked what in the world they were. What's really embarrassing is when you've given someone a piece of a rose in a different climate and then ask them what that gorgeous rose they have is. "I got it from YOU!" OK. I'd wondered for a long time how they bred anything from Rosarium Uetersen. In my inland, valley heat, there are no sexual parts. The entire flower is usually packed completely full of petals and petaloids. The color is also a neon, poster paint coral pink. Then, I saw it along the coast...pastel coral with three or four rows of petals and an enormous center of lush, golden anthers full of pollen and a stigma crying out for the taking. I asked a friend what it was and she looked at me as if I had twenty heads. She bought the thing from ME at the nursery I managed back then, but I had never seen it grown in the cool, damp, only the hot and dry. That's why identifying roses from a photo taken in conditions you're unfamiliar with is so bloody difficult, unless the rose is so unusually distinct, nothing else could come close to looking like it. Enjoy! Kim

Kim is right, it's a red carpet. I have a few of them, but my dark pink carpet roses for some reason bloom much more than the red ones, their re-bloom speed is more like Knockout roses. I also have some very light pink (almost white) carpet roses, very pretty, but they don't repeat well in my garden.

I have had Jim Sproul's Eyeconic Pink Lemonade for 3 years now and I love it. It has great rebloom and is very healthy for me. It's also remarkably winter hardy. Which was in question early on because of the Rosa Persica in it's background.

I got Bulls Eye late last season and it never bloomed for me so I was a little surprised that it came back after that bad winter. It's planted in the ground now and putting on a lot of growth and has bloomed a couple of times. It's been healthy so far. Of the two I still like EPL the best because BE fades out to almost white really fast.


Thanks for the replies everyone. I have a tropical garden blog if anyone is interested (shameless plug):

Ah, Bayourose- you just made my day!! I have done a lot of mid-summer planting of roses in my zone, Heather, and sadly I only get winter survival on substantial sized pots anything after about June. I can plant Roses Unlimited gallons from their July sale without particular problems, but we don't get reliable snow cover and even with protection bands are simply not feasible for me this late in the year.
After last frost, however....now THAT I can order with a clear conscience!!
Off to blow my weekly budget...

Pictures would be a big help but there are a couple of possibilities that come immediately to mind. They could be Pink KOs that were mislabeled as red. But, it could just be a matter of the conditions they are growing in as well. Weather, soil and culture can all play a factor in bloom color.

I can't really say about the business-end of David Austin's business nor about any other company/business, but I can say that to me, Austin roses are NOT " those bloated and frilly monsters." They are still my favorite category of roses--though I like a lot of other kinds of roses also.

Susan I think death takes a few years. The ones in downtown Franklin that I was watching were going on 3 years before they finally dug them out because they got so ugly. The multiflora seem to hang on for a least that long as well.
I've linked a story that was circulating locally last year. It might help you with your neighbor.

We did not get all that heavy rain, thank goodness! We did get an inch or two I believe. I think my roses were not getting enough water, as soon as I spotted the brown leaves I watered them really well. Now I know they'll be fine, they're looking better already. Thanks

"Although California has many different species of root-feeding nematodes, the most damaging ones to gardens are the root knot nematodes, Meloidogyne species. Root knot nematodes attack a wide range of plants, including many common vegetables, fruit trees, and ornamentals. They are difficult to control, and they can spread easily from garden to garden in soil on tools and boots or on infested plants. "
H. Kuska comment: I wonder how many people that think (or are being told in this forum) that they have "heat" problems with their roses actually have root knot nematode problems?
"Aboveground symptoms of a root knot nematode infestation include wilting during the hottest part of the day even with adequate soil moisture, loss of vigor, yellowing leaves, and other symptoms similar to a lack of water or nutrients. Infested vegetable plants grow more slowly than neighboring, healthy plants, beginning in early to midseason. Plants produce fewer and smaller leaves and fruits, and ones heavily infested early in the season can die. Damage is most serious in warm, irrigated, sandy soils."

We had hailstorm also. My roses didn't get damaged too bad but large leaves plants like hostas, grasses were torn, and had holes from the hail. Very weird summer, sometimes heavy rain, followed by long dry spells, fall type weather starting to settle in! Short summer!






Thanks, Henry.
That Figure 3 shows one side of a compound leaf most affected and the terminal leaf beginning to be affected. It almost looks the opposite of vein clearing.
The two P. fructiphilus in Figure 2 are the whitish long things ....not all the red globules.
