I'm new to growing roses. I have a Miss American Beauty rose bush that bloomed beautiful hot pink roses this spring. I've had some lovely new growth, and yesterday a brand new bloom! However, this new bloom is pale pink and has a strong beautiful scent. The hot pink roses I had earlier in the spring did not have much of a scent. What in the world is going on? I came across the term "sport roses" but I know nothing about that. Any insight is appreciated. TIA.

Sports are a genetic mutation that occurs while the plant is growing. It happens in all plants and more frequently than we realize. Many things can cause a mutation to occur, soil, fertilizer, weather or just because genes mutate. lol! The mutation can happen anytime and anywhere along the new growth, in the stem, thorns, leaves, or blooms. Most of the time it is a one time occurrence and doesn't reappear. Occasionally a mutation will be stable and will repeat from that branch again and again. Mark the branch with the different bloom with a ribbon and wait for it to rebloom to see if the sport is stable or not. Don't worry about it because it will not harm your rose in any way. It is a totally natural occurrence. If that cane does continue to have the different color blooms you can take a cutting and try and root it. You will have a whole new variety of rose all your own!

The parents for Miss All American Beauty is "Chrysler Imperial × Karl Herbst' " both are a red rose. And that light pink sport is very pretty. And if it has strong scent. Maybe it's a new found winner. As @seilMI said you may have an all new rose that no one else has any where. To me that would be awesome. As she said mark it. And if it reblooms the same color. Take a cutting of that cane and dip it in rooting hormone. And plant it. Hopefully it roots. And you'll have an all new rose variety. That you could name.

Do you know what rootstock the rose is grafted to?

I thought of that too. But if you look at the pic. It's coming from an existing cane. Like a basal break.

The pink rose is coming from a cane that is straight on the graft. It could be the rose used for the graft. Autumn, where are you located? That could help identify the rose used for grafting.

I thought it was coming from an already grown cane.

@autumnrosemom could you take a few pictures of the stem from that pink flower and follow it down to its base. And take a picture.

What other root stock is used for grafting, other than Fortunia(white rose) and Dr. Huey(red)

Multiflora is also pink and Pink Cloud is used too. However, I don't think any of those have that form. I do not think this is root stock.

De la Grifferaie can look like that at a certain stage in the bloom's development.
