In addition to planting native milkweed host plants for monarch caterpillars it is also important to plant nectar-rich plants for adult monarchs. Adult monarchs are dependent on nectar plants as a food source during spring and summer breeding, fall migrations, and during overwintering.
The Xerces Society, in partnership with the National Wildlife Federation and Monarch Joint Venture, developed regional monarch-specific nectar plant guides for the continental US. The plant species included in these nectar plant guides are based on monarch nectaring observations compiled from numerous sources, including published and technical reports, research datasets, and personal communications with monarch researchers, botanists, and other experts.
