This is my contribution to Cee’s Fun Foto Challenge prompt: Flowers: Blue or Purple.
I thought of two blue flowers that I find visually interesting, Borage and Chicory.

A Borage flower in a garden in Nantwich, Cheshire, England in the mid 1990s. Photographed with a 300mm telephoto lens to isolate the flower and buds from the surrounding plants.

A Chicory flower on the South Bruce Peninsula, Ontario, Canada last September. Photographed with a fast portrait lens to help isolate the flower from the surrounding plants.
