In Fremont, CA, Sheila's Perfume can't be beat! It's hardy, disease resistant, shiny green leaves, very vigorous grower, flowers like crazy, smells heavenly, and the color is to die for if you like bicolors. It varies from pink-yellow-peach, to slightly deeper in fuller sun or mid-summer, but the color is vibrant without being strident and gradually shades from the edges, never looking abruptly garish like some bicolors. The form is beautiful hybrid tea-like. If you were stingy, you could say that if there were more petals the flowers would open slower and last longer, but with so many of them, who cares!
