Our Callicarpa berries are anything but blue. They're a particularly
vivid shade of screaming pinkish-purple, a color not found elsewhere
in nature, I think, except in orchids and some tropical fish.

Callicarpa does not have berries, but drupes.
I am wondering if the blue color is somehow connected with this.
Prunes also tend to be blue and also are drupes.
Just idly wondering.
