Once September arrives, pollinator plants become increasingly more difficult to find.  However, a native plant that helps fill that void is an herbaceous perennial known as late boneset (Eupatorium serotinium).

       Late boneset provides nectar to a wide range of pollinators such as native bees, moths, and butterflies. 

       In addition, it is the host plant for the clymene and other species of moths.  The dorsal side of this moth is most distinctive.  Its wings are creamy and marked with bold black markings that resemble a cross. To me, the markings look much like the symbols seen on the shield of an English knight.

       While I often see boneset blooming in old fields and along country roads, I rarely encounter it in backyards.  Interestingly, my daughter recently found one blooming in her suburban backyard.  She finds this volunteer so fascinating; she plans to let it continue to prosper.

       Since the plant is easy to grow and is deer resistant, it is a valuable addition to the backyard of anybody interested in promoting native pollinators.
