I have been trying for well over a month to get a blue rose to appear.
I followed the steps of making a hybrid red rose through an orange and purple rose

and planted the hybrid reds roses together, buried fertilizer next to it every day, and watered it every day

But I have yet to see any blue roses. What, exactly, is the probability of getting a blue rose?
I want to make a blue rose myself rather than get it from someone else, but I admit I am getting a bit frustrated.
