In Fremont, CA, Sheila's Perfume can't be beat! It's amazingly vigorous, disease resistant, shiny leaves, good hybrid tea-like form, medium petal count, flowers like crazy, and smells wonderful. The color is a vibrant to medium yellow edged peach-pink (more vibrant/deeper in hot weather/sun), gradually shaded at the edges, never garish like some bicolors. If you were stingy, you could say that if it had a few more petals, each flower would open a little more slowly and last a tiny bit longer, but with so many, who cares!
