Mistflower is a long blooming native which blooms heavily from August to frost.  Eupatorium coelestinum looks like an Ageratum, as it is crowned with delicate clouds of violet blue flowers.  This is not a plant for the faint-of-heart, as it spreads vigorously to make a good groundcover mat for shady and sunny locations.
