In Fremont, CA, Sheila's Perfume can't be beat! It's amazingly vigorous, shiny leaves, disease resistant, good hybrid tea-like form, moderate petals, blooms like crazy, and smells wonderful. The color is a vibrant to medium yellow edged peach/pink, a little deeper in warmer weather/more sun, with gradual shading at the edges, never garish like some bicolors. If you were stingy, you could say that if there were more petals, each flower would open a little slower and last a tiny bit longer, but when there's so many, who cares!
