"Marmalade Skies" roses are pink/white instead of orange!
I have a young "Marmalade Skies" rose plant (a floribunda variety.) It's supposed to have "clear, red-toned orange colors" that "last well through the life of the flower."
What actually happens is that the buds and very young flowers are orange. Then they turn a pinkish orange, then pink, then the petals are both pink and white!
In the same bed I have a new "Shockwave" yellow rose plant whose flowers also get paler with time, but which says yellow, and a very old, large rose plant with bright red roses that don't have a problem (not sure which kind, but could be Liberty Bell.)
What could be causing this? Could I be overwatering? Under fertilizing? Something else?
