Thanks Marybeth for adding my pictures. These new stems, as you can see, are shocking pink not true red. The other main difference is that these new serrated petals have no scent whereas the red petal roses have strong scents. This new looking blossom is not on the plant that has spotted leaves that you see in the link but is in the same bed.

IF it is a sport what should I do?

I highly doubt the serrated petals would be do to the other problems. It's a beauty of a bloom. Has this rose previously had red blooms on it. The bloom is like that of Pink Grootendorst but not so much the foliage as far as I can see.

Sharon If that was Pink Grootendorst that could explain the leaves on that one at least. Are you where all the rain has been? Rugosa hates too much water, fertilizer or being sprayed with anything but water. It's leaves turn ugly rather quickly.

Patty, this is what the bush normally looks like

I think Sharon mentioned that there is currently no problems with the leaves on this plant. However, it is in the same bed with plants that have leaf problem. She has quite a few roses in that bed.

Thanks Marybeth. Yes you can see the bush here has four long canes with red blossoms as the end. I cut these back apprx 24 inches to have them in a vase. Two of the stems put out the serrated hot pink blossoms on the stalk after it put new growth out from the cutting. The other limbs that were cut back has not flowered yet to know if they do the same thing.

I do bot know what a Rugosa is. I think this is a hybrid tea. The mother plant was obtained at home depot years ago. It is still putting out regular red roses. This hot pink is only in the last bloom cycle. If it was just a different color I might have thought it was weather related, but the fact that it is a different color, with different kind of petals, and has no scent as opposed to lots of scent has me concerned.

I am just hoping it is a sport and not some abnormality because I am having the abnormality in leaf coloration in other roses in same bed, but without any change in color, scent or petal shape.

Thanks to everyone who is helping identifying this

And especially to Marybeth who is kind of enough to post pictures for me.

Then the next thing too check are ancestors if the roses name is known. Or you have a gorgeous sport

How exciting,

I am wondering if the new colored rose is growing from the own root rose or the grafted one or both? I think it might be helpful to photograph the base of the plant where the pink variation is stemming from. You mentioned the pink roses are growing in two places?

My first bet would be this is a sport, and if you want to keep it be sure to not remove the stem its growing from or you will likely lose it. Some people tag the stem to keep track of it for the next growing season to see if it is in fact a stable sport. ( if you do this I would make sure its something light that won't damage the stem) if the sport is stable it could be fun to take cuttings or try air layering it to reproduce this rose as well.

Seeingreen, the pink is on the own root rose. The own rose is about two years old and has put out red roses for a year. All of those blossoms looked like the mother plant. The whole bush shot as seen above is the own root rose not the grafted mother plant. I will try and get a picture of the stem shot. As far as I can tell the leaves of the new pink rose looks pretty much like it always has. These two pink blossoms are on canes that have already produced red blossoms. I cut the canes back about 24 inches with the red blossoms attached to put them in a vase. Not long after the cut it started to put out new growth as usual, but when it opened I got the hot pink. At first I thought the color was odd while it was in the bud, but I was more worried about some leaves of another nearby rose plant I and I didn't pay too close attention until it opened. Then I noticed it was hot pink with serrated petals. and the absence of scent, because this bush is highly scented..... I couldn't/can't detect anything even with my nose buried in the blossom.

You say not to remove the stem, do you mean not to cut this blossom off the plant that is what I did for the red... and got this..... I'm afraid to cut it now.... if I do cut it do I only remove the flower

This bush - at least in the past dose not branch out. It does( or has) continued to put growth straight up from where ever I cut. It normally has one flower at the end as seen above.

The plant this was coming off of is from a cutting of the mother plant and not a seed? I could understand the variance if it were from a seed, but if it is a cutting it looks like you have a beautiful new sport.

Posting for Sharon for seeingreen

Thanks for the photos!

Looking at the first photo, I would have thought right away the swelling at the base of the rose in the first picture, is the bud union, and the rose cane directly next to it, root stock, because it looks like its coming in under the graft..... But since you say, it is the rose cutting thats growing on own roots that has changed color. I would agree it is likely a new sport. If it is a sport, which to my understanding is a sort of reshuffling of the plants genes; the sport may not be throughout the entire plant. So you may want to be careful what you trim off, depending on where the sport begins. Part of the plant may still bloom true (looking like the mother plant) :D

Ok. Thanks Marybeth and seeingreen.
