If I ever get to design a garden again, the color scheme will be purple and white.  I had no idea there were so many purple-blooming shrubs.  I can just imagine all these different purples — from the itty-bitty clusters to the morning glories to lavender to whatever this is — with white bougainvillea and white hydrangea interspersed.  Purple and white seems so crisp to me, and the varying leaf colors, especially the chartreuse, just set them off perfectly.  Ah, joy.
