Help Monarchs, Plant Milkweed!

Monarchs are on decline across much of North America. This is due to a myriad of factors including habitat loss; use of synthetic fertilizers, pesticides, and herbicide; and climate change. One of the best things YOU can do is plant milkweed host plants and nectar-rich native perennials. Maine Audubon sells native plants; order online and schedule plant pick up at our Falmouth or Holden/Greater Bangor location.

Monarch caterpillars are totally dependent on their host plant, milkweed, of which we have two varieties available for sale (listed below). In addition to milkweed flowers, monarch butterflies get their nectar from a variety of native, late season flowering plants. Five of our best late season flowering plants are listed below.
