This is Caryopteris divartica “Blue Butterflies”, another Japanese edge of the woodland perennial blooming now in my New Boston garden. This plant can become very large, and becomes a die back shrub in our winters, coming back from the roots in spring. It can take half sun. It is also a determined seeder, and little ones pop up all over, so there will be plenty for your friends-

A cosmos in my dry border.
