My bushes range from white to deep raspberry to lime green trimmed in dark pink,I have notice most flowers are fading then you have a late bloomer. I to ,have many colors around my house. When the bush is purchased it is done so by a color that interest me. Then the key is to feed the bush what it needs to stay the true color for which it was purchased. Feeding around the drip line.My cone white has the most unbelievably large flowers.You can Google these plants and see what each needs to bloom there true color.
