At least the May Night salvia is a different shade, and even more so, the Salvia 'Caradonna'.
And at least they are a little different texture, but can you see the Salvia daghestanica here?
Betty Corning has a similar color, but it's more purple. Which makes me realize that the good thing about all this same color, is that it ties the garden together. I guess you can tell what color I like. That is, until the roses start blooming in earnest.
