From the Dahlia Trial Garden, at the Minnesota Landscape Arboretum.
This one really strikes me like a Pinwheel!
For many of these Dahlias, I had to ignore the rabbit fence that surrounded the garden… I’m hoping those were mainly to prevent rabbits and other animals from eating the dahlias, and not meant to keep visitors from walking among the flowers. But the dahlias are fairly large now, and most of the good ones were quite a ways in from the fence…
