Monarch butterflies (Danaus plexippus) were in abundance during my recent visit to Manitoba. While the caterpillars feed exclusively on milkweeds (Asclepias spp.), the butterflies have a more varied palate for sources of nectar. Perhaps most favoured of the many flowers that the butterflies visit are species of Liatris (the “blazing-stars”), such as this meadow blazing-star.

Dr. Tom Barnes of the University of Kentucky writes in an article on attracting butterflies with native plants (of Kentucky!) that Liatris ligulistylis emits a specific odour for attracting monarchs. I wish I would have known that prior to my trip, as I would have patiently waited for a monarch imbibing nectar from one of these flowers for a photograph. Next time.

If you're a gardener, Kim Hawks of Brooklyn Botanic Garden has some good advice on growing Liatris.
