Ok so I planted a knockout awhile back. It flushed some flowers. I then deadheaded it. And it never really bloomed again. Like 3 or 4 flowers. Then went into a stall. And did nothing for weeks.
I dont want it to spread to my other Rose's, if it is,
These are from when I planted it. It had bright pink knockouts.

Now the flowers are red and completely different. And it's not a new cane. It's from a basal break from an older cane. That flowered pink before. These are from today. You can see it doesnt look anything remotely close to the original. And I could understand if it was a new cane coming from the soil if it was a grafted rose. But it's not. It's coming from a cane that already flowered pink knockouts. And I understand color change with temperatures and humidity changes. But it's a completely different flower.

This growth looks somewhat normal.

More weird growth

No super thorniness, so according to the rosarian that looked at ours (even though it was much thornier than normal), it is not RRD. Maybe RU drift?

I have to agree with Rosemary. There's no sign of the hyper-thorniness of RRD, Nor are the canes larger than the ones they are stemming from. What ever this is I do not think it is RRD. Could be RoundUp or any herbicide damage. I would cut off the affected canes and see what grows back.

Any chance Round-up has been used anywhere in the vicinity where a breeze could have carried a bit to your roses? It will deform the bush and cause weird growth and blooms if you are lucky enough to still have blooms.

Maybe the strange rose is a mutation?

It was planted on june 7th or 8th.
This is it on the corner with flowers. Pink knockouts. I'm like 97% sure that it was a knockout. Not double knockouts. Bc I bought it when I bought a coral knockout. It's on the other end there on the right. But either way you can see the pink flowers. Bright pink. And then the pic I just posted of the red is a single set of petals. 5 and then a center short petal covering the inside. These are from today. The only thing I've done to it other than give it water, if it needed. Was dead head the pink flowers as they died off. So maybe it is just a weird mutation. From one of the parents or the mix of the parents. These are made produced on a huge scale. I'm sure things go wrong sometimes. It does have a few buds on it. I'll let them open and see what they are. I jus didnt want something happening to my others. And it does have 3 new basal breaks coming from way down low on the main canes. So it must be healthy. Maybe just odd new growth.

I think this says it all about sports. https://davesgarden.com/guides...

My Midnight Blue created a totally white sport. Other roses of mine have had this happen as well.

Weird weather extremes can cause abnormal growth. Which could explain the leaves. In your case the red flower is probably a reversion not really a sport. Your pink KO is reverting back to its original red KO. It may continue to bloom red or go back to pink. There is no way to know until it blooms again.

I would watch it like a hawk. Rrd does not present all symptoms at all times especially early on. That growth does not look right.

So heres a little update. It has opened a few of the buds. And just as I suspected. Bright red. Like Mr. Lincoln red. Not anywhere remotely close to Coral/ and or pink. Nor do any of the flowers look like a knockout. I think it may be best to just pull this bush. But then I have the problem of not knowing what was wrong. I've heard roses dont do well in places that roses once were. And if it's a problem below the soil line, I dont want it to kill another rose. But i hate to leave this big area with no flowers right on the corner. I guess i could replant it somewhere else. And see how it goes. If it keeps growing like crappo then I know it's not the soil.
