Pink Knockout Rose gallery

Pink Knock Out.™ We have had cool fall temperatures and I believe that has caused the variegated (blushing) coloration. This same rose turned a pure pink about 2 weeks later. Foliage also turned maroon. Notice the close-up of the foliage. Whitish deposits on the foliage is calcium deposits. We top water either night or day at the farm but never sprayed for bugs or disease.
