Additional Notes about Buttonbush:


Native to Ontario and other parts of North America.

Larval host for numerous butterflies and moths, including the Titan Sphinx and Promethea Silk moths.

The flowers supply mid-summer nectar for many species of bees, including some specialist bees. The seeds are enjoyed by large and small waterfowl.

The foliage is poisonous to people, pets and livestock, so deer will leave it alone.
