A plant native to southern Ontario, it also grows fairly well in the Backyard Garden at the FWG. The name suggests that it is a magnet for butterflies, but we have not seen many visit it in the years we've grown it, though we have seen other insects sometimes nectar there, as this sweat bee is doing.

The phlox in the garden today, had attracted a hummingbird moth (Hemaris thysbe), the large reddish sphinx moth that is one of the most un-moth like of insects!
