I already knew you could obtain pink roses from breeding white and red roses together. I looked at a couple of flower combination guides before uploading this thread.
Your reply also implies that it is not possible for pink roses to be produced from breeding two red roses together. If my memory serves me right, I was able to obtain at least one pink rose from my batch of pure, unbred red roses which would make that claim false.
Do you have any knowledge of hybrids gained from personal experience/trial and error rather than from guides?
