Gardeners' Notes:

The Pollinator Party Palace. In the fall of 2013 a plant volunteered in my front bed that I thought was a Veronica. So I transplanted it to an appropriate place on my border. After it emerged and grew in the spring of 2014, I soon recognized that it was not a veronica. I was going to pull it, but decided to wait and took a branch to a plant identification expert at The University of Cincinnati, fully expecting him to tell me it was a noxious weed. Instead he told me it was Eupatorium serotinum, a native plant. He said it would have a pretty white bloom in the late fall and that it would attract pollinators. He urged me to keep it, so I gave it a home in my garden. I discovered its odd common name, Late Boneset. In Late August it bloomed. The bloom is attractive, but not spectacular. What makes this plant notable is the way it attracts pollinators. I call my Eupatorium serotinum the pollinator party palace. So many pollinators come that the plant literally vibrates with the activity of small bees, beetles, wasps, and small butterflies.
