The gardens on Mackinac Island were also an inspiration for me. I don't have the space, sunlight or time to recreate such lavish displays, but I did get some ideas for color combinations for next spring's annuals. One of the B&Bs on Main Street had gorgeous dahlias.
I don't grow dahlias. In Michigan, the bulbs need to be overwintered inside, and that seems like too much trouble. I am fond of the flowers at least partially because they remind me of Aunt Dahlia from the P.G. Wodehouse stories.
