Rainbow Knockout Rose question

[Bec]

I have several varieties but recently bought a rainbow. When I bought it, it had light pink flowers with beautiful yellow centers. It started to bloom again this past week and all the flowers are dark pink with no yellow anywhere. I am baffled, I saw the beautiful rainbow roses with the yellow now they're gone, how is this even possible? It just switched colors on me?

I would give it some time and see.

I don't have any knock outs, but I know some rose colors change with temps. Like as in when it is hot the buds/flowers they produce are different than when it is a cooler time of the year.

But you might also want to check on what kind of root stock they are one.

Thank you! The crazy thing bloomed again...all dark pink, 1 lightpink with yellow center! I like the variety! Guess i just have a unique plant!

If it was grafted, the rootstock could've taken over and the top died out. Take a look at your plant and see if it was grafted...if there is anything still alive above the graft, you might be able to save your rainbow and eliminate the pink.
