Dr. A. S. Thomas.   New Roses in Victoria 
Pink Emperor, HT. (Hennessey 1958) Big, very double well-formed blooms in pink and salmon pink coloring. Its eighty or more petals cause it to open so slowly that it is exposed to weather hazards. Probably best in warm climates. Growth is good but apparently not tall.
