    A few years ago at a master gardener class, one of the students came up to me with a wonderful story and photo regarding this plant. She said that the bees loved the flowers so much that she could pat the bees with her fingertips while the bees were eating. She had a great photo close-up of a her fingertip stroking a bee sitting on a buttonbush flower. It made me wish I had a damp place to plant buttonbush! Then sometime later I was out in my yard one spring when some of my bee-favorite flowers were in bloom. I got to thinking, “Why just Buttonbush?” So I screwed up my courage, found a bee feeding on a flower and started stroking it with my fingertip. The bee didn’t even notice and kept right on eating. Pretty fun and even more reason not to be afraid of bees in the garden!
