To the right of the dwarf pink azalea is a tall white one. This picture shows a blending of the two. I guess the white one seeded into the pink one. It is also possible to see a mimosa bloom in this picture.
I've seen a blend of pink, white, and lavender crepe myrtles. I don't care much for the lavender, but mixed into the same clump with pink and white, it is like a very large bouquet.
