Cynthia Brooke, with buff on the yellow ground is a rose that is worth while.  It makes a really good standard and the flowers are better when thus grown than on the dwarf.

R. Marion Hatton.  The World's New Roses
We are just getting two of MeGredy's, which you may already have - Cynthia Brooke and B. W. Price, two more of McGredy's beautiful flowers on woozy plants. The former has 4 inch open flowers of soft golden yellow, with a pinkish reverse. The petals have interesting wavy edges. Fragrance is again very mild.... it is about time the McGredy's paid more attention to their plants.
