Summary
Conoclinium coelestinum, commonly called blue mistflower or wild ageratum, is an important part of the SBG’s late- season pollinator buffet.
This ‘celestial’ beauty boasts clusters of small, fluffy purple/blue flowers that attract butterflies and provide a shot of vivid color as the rest of the garden begins to fade.
In a sunny, moist spot, it will spread readily by rhizomes, creating soft drifts that assure you of a well-stocked pollinator pantry– and a stunning fall display!

Ecosystem Connections
Although not a host plant for caterpillars, blue mist flower ‘hosts’ a wide array of pollinators who are looking for a good late-season nectar source, including migrating monarchs. It’s also noted by pollination ecologists as being of special value to native bees.
