Don't get me wrong I love it! I'm just curious.

I bought these on clearance last year from lowes. I know they loved where I placed them because they instantly came back to life. This year I have over 45 buds on it and a few have bloomed with.. double or triple inside of one bud! Their color came out even brighter as well. My neighbor thought I got a whole new bush. I will post a before and after photo. But I'm wondering why did they do this? Will it happen again next year? Last year was all single blooms.

Wow! Did one bud produce the bloom on the lower righthand side of the second photo, or is that a cluster?

They were all one bud! That is why I'm just amazed and confused, haha. It's turned into something I've never seen. I can't wait for the rest to bloom. I will take a before photo today of all the single buds.

I had no idea this stuff could happen so I have no before photos of just the buds. But I know they were singles because I had some aphid trouble and was trying to get rid of them last week.

I just went out to check. My clusters have not bloomed yet. Here are some photos of the twins and triplets stems.

I'm sorry for talking so much. Just one question. Should I cut off all the leaves with spots? I live in Washington state. I read it's a bacteria.

Where do you live? What kind of weather have you had over the past 6 or 8 weeks? Have you used any chemicals or fertilizers? There are many reasons why a bloom can change its form. Without further information it would be hard to say what it might be.

Black spot is not a bacteria. It is a fungal disease. You can remove the spotted leaves but that will not prevent it from returning. There are fungicide sprays you can use but they take time and repeated uses. It would help if you cleared out all the grass around the base of the plant for at leat a foot away.

I believe what has happened is called fasciation its a mutation. It happens in daisies a lot. I had a rose last year that done it. It was two buds that didnt seperate. They stayed connected instead of growing apart.

My apologies! I meant fungus. I live in tacoma, Washington. It has been rainy, sunny, and rainy. Haha. It will be sunny starting today till Saturday. I have not used anything on them. Thank you for the tips!

Oh very interesting! Thank you. I've contacted a local nursery.

If you had the cold spell during the time those buds were forming that could definitely affect their growth. The time when the buds are first forming is the critical time. That's when changes will happen genetically that you can't see. Then they show up later on when the bloom opens.

I don't think this is fasciation. Although weather can generate fasciation, from the side views I don't see two hips fused together. These are just double centers. The rose Double Delight does this frequently. The petals just don't develop in the proper furled order and cause more than one center to appear.

Variations in color happen all the time. MANY things can cause a rose to appear lighter or darker in color. In cold climates people often marvel at how much deeper their roses look in the fall when the weather starts to cool way down. A little less or more fertilizer can cause it. Any change in the soil conditions will change the colors. As I said, many things can cause it. It does not mean that there is anything wrong with the rose or that it's unhealthy.

Seil's right (of course). This isn't fasciation. The term I've usually heard used for it is "bullnosing". Bullnose.

It is as Seil said, a double center ... and yup, Double Delight is notorous for it (which is why it fell out of favor as an exhibition rose. If it doesn't bother you, don't worry about it. It's not anything pernicious.

And yes. Changes in weather can make a HUGE difference in rose colors. For example, these blooms are all "Old Town Novato" -- in different weather.
