Looking a lot like small wild sunflowers, Jerusalem artichoke has found a happy home at P.J. Hoffmaster State Park in Muskegon, Michigan. The colorful flowers, sometimes called sun root, bloom late in the summer. I find a view with dark woods behind that I know will become a simple, black background when I expose properly for the flowers.
