I am trying to grow Black Roses and "Special" Red Roses in my town. I have tons of X patterns of strictly Reds and X patterns with 1 Orange in the middle of 4 Whites to produce the Special Reds. My strictly Red X's are producing a few Blacks but mostly Pinks. My Orange and White X's are producing Red, Yellow and White. Is this normal for flowers to create colors that they shouldnt be? For instance why are my all reds making pinks and why are orange and white producing yellows? One thing to add is my towns native flower is Roses, could that be why or is it just completely normal? Thanks in advance.
