Color 'blotching' is most likely to be observed with maiden blooms of F1 hybrids and can manifest itself on either the face or reverse. Most times it disappears with the second or third blooming cycle--but not always. I still have a 10 year old +/- growing here as a example to show only. I never tried to breed it out as I consider it a bad feature and those that show it after the second or third year are culled and destroyed. It differs from virus in that a color break caused by a virus reads through the petal from face to reverse. The blotching or blemish occurs only on the surface and does not go all the way through. I should note that my observations are with my work with Div. VI.
