Vita Sackville-West called her splendid white garden "the grey, green, and white garden" in her book, In Your Garden. She found a white garden needed not only white flowers but also silver and green colors. In the same way, I noticed white and silver colors were necessary for a blue garden.

Blue colors and white colors look like jewelries.
In July, a blue garden of my dream appeared.
Light purple is Delphimium. White roses are Mme.Hardy.
English rose, Redoute. Blue flowers are S. guaranitica.
I love especially the blue color of S. guaranitica.
