I agree that true blue is one of the most coveted colors for the garden. And delphiniums are among the best at delivering true blue. I'm thinking it's time I give them a try - at least once I do the mulch thing here.
I recently saw bachelor's buttons blooming with California poppies along the street and I decided I need more of both of those colors in the garden. Thanks, Toni, for the reminder!
I'm afraid that apart from their fragrance, I've not been very attracted to the so-called blue roses since they are barely purple or violet, let alone blue. (Rembember ROYGBIV? There's a whole, almost forgotten color between violet and blue, indigo, and it deserves its own space, probably also to be brought into the garden by delphiniums.)
