Roses just sometimes pop out different looking blooms, different shades, different forms, etc., it happens. Any kind of change in it's environment during bud set, and that was weeks before it opened, can trigger a change in the ultimate results. If the weather was a little wonky the week it set that bud or if you sprayed something at that time it could have affected it. Mark the cane and watch how it blooms in the future before taking any actions. It's probably just a one time occurrence.

This is so sad and loving and beautiful. We were lucky to find a baby squirrel and raised her until she was old enough to go out on her own. Two years later she came back and brought her children. She left and they stayed. This year she came back again. We also raised a tiny baby wild mouse and she stayed with us for over three years.
When our beloved cat died we buried him with a spray of blooming Souvenir d'un Ami roses against his chest between his paws.
Your tribute is so heart-warming and I'm getting teary. Thank you for caring so much.

A Knock Out isn't a rose I'd give "infant slack" time too! They are bred to be high performing right out of the box and if they aren't I can't imagine it would be any reason other than it doesn't like the spot it's planted in or it is a "lemon" specimen. Both reason would have mine gone and/or moved pretty quickly. (Says the woman who yanked one out last week!)
I totally get being patient with a something not bred to be so vigerous, but KO's are not a "1st year sleep, 2nd year creep, 3rd year leap" kind of variety!

Re shade: back when the Chihuly exhibit was at the Atlanta Botanical Garden, some of us got together to see the roses and his glass. In back of my favourite pond with some very subtle glass colors, Jody and I saw a rose blooming not in the rose garden. So, of course, we had to go see.
The rose was taller than either of us (not that hard for most roses) and wasn't heavily leaved out, but it was blooming self supported in dappled sunlight. J sought out the label at the bottom and it was Knock Out. It didn't look like all the other KOs we had seen, but was adapting well to good soil, dappled sunlight and benign neglect.

Hmm. Glad to hear that it hasn't reverted to something else. These are new basals, and I didn't want to have to cut them off. It's been getting plenty of water from a drip hose until about a week ago when it started freezing. So it's not too hot, although I may have let it dry out recently.

Henry,
Do a scientific search for the papers by Kaminska et al. who have written very, very much about the phytoplasmas in Europe and be sure to see the paper about rose disease in a greenhouse in Poland . Of the Kaminska papers I was able to download, all found phytoplasmas and none reported finding any viruses.
There are also two papers about some sick roses in a bed in China that the authors tied to Pawlonia phytoplasma in a tree adjacent to the infected rose garden.

Ann I am familar with the rose phytoplasmas litererature including the Chinese (and including the 2010 U.S. paper which I posted in this forum).

I started the present thread for information purposes. Someone is still claiming that rose rosette virus is not a virus but a phytoplasma.
Here is a link that might be useful: link to earlier thread that reported that RRD was a phytoplasma.

We have both Katydids and Grasshoppers. Some years worse then others. For me Grasshoppers are far worse then Katydids, but then our Grasshoppers can get very big and have an enormous appetite. Mostly what I see Katydids doing is sitting on a rose. Mostly what I see Grasshoppers doing is eating a rose. I leave Katydids alone just because they don't do much damage that I can tell.....Maryl

Gee I thought Katydids was just another name for grasshoppers...
I have no doubt this Katydid ate some of the rose bloom.
But I see no other damage anywhere else.
So far they have not been much of a problem here either.
Hope it stays that way...lol

I never encountered mildew until we moved to Pasadena and then I discovered that it is the biggest problem here. I thought it would go away after June but it didn't and some roses that were particularly susceptible were literally shriveling up they had it so bad. So I decided to spray with potassium bicarbonate and it does work. It wont help destroyed growth but new growth will be protected. As far as I can tell it is organic and hasn't hurt any bees or other insects. The product is GreenCure fungicide and it is available widely but it is expensive.

Some roses are like that -- at some times of the year, they get a touch of mildew. No biggie.
Some roses have NO resistance, and mildew at the drop of a hat. And the problem is far worse in some areas than in others.
Actually, if you are (like Henry) in an area with fairly high mildew pressure, you have two basic choices . . .
1. Spray regularly.
2. Keep roses that don't mildew.
Our option is 2.
Why mess with roses that frustrate you? Prune 'em with a shovel, and discover a rose that doesn't have that problem.

Take a look at this thead on best white landscape roses:

For taller Perennial plants, try Lavender Provence or Grosso. They are almost evergreen in my zone 6b climate. I also grow 8 other varieties, but these two are the tallest . For most of these varities, I get a decent second flush (going on now) if I cut the flowers early enough in the season, but not so much for these two.

There is "white out" which is not a knockout rose but is bred by the same person Bill Radler...
Sunny Knockout starts out yellow but quickly fades to white...

Picked up 12 roses from Steve & his kind wife Kim today. Had a hard time choosing, my wonderful husband who came along for transport kept me focused! Thanks Steve and Kim, made for a great birthday for me today!
Strawberry, would have been neat to see another Gardenwebber there!




Do a web search for the pest called Chili Thrips. They are a world wide problem with many, many host plants and are especially bad on roses. They destroy foliage and without the foliage, roses suffer badly.
Two of the bits of new growth on your well established rose look good, but the one at center shows damaged leaves. That the buds are coming so low implies that the rose is stressed (that we see so few leaves is another clue.)
The state of Florida in the US has several good websites about these thrips and may help.
I agree with Anntn. It looks like chili thrips damage. We see it often here.
