Sabrina, don't panic!!
The success rate rooting florist roses is, in my experience, between 20 to 30%.
Here are three out of eleven which I rooted this past winter. They were a mixed bunch from Aldi
These three cuttings, which I should never have put into one pot, are from cuttings I rooted two years ago. The only reason I put three in the pot is because I didn't expect them to survive the winter outside - but they did!! I stuck 10 cuttings of these and 9 took but these are spray roses. I think it is Interplants 'Flash Dance'
This is Esperance, also stuck two winters ago. Two out of 8 cuttings took. I planted one in the garden and potted the other. This is the one that was potted and overwintered in the shed but the one that overwintered in the garden is doing just a well.
So, as I said - don't panic! The more cuttings you stick, the greater the chances of getting some rooted. It can be done.
I will however repeat what I have mentioned before: you will have much greater success grafting/budding florist roses than trying to root them.
