So many common names. For these charming flowers I use the common name, Wild Ageratum. Its scientific name was recently changed to Conoclinium coelestinum.

These are herbaceous perennials that grow to between 1 and 2.5 feet tall. Leaves on the stems are opposite, and those stems are topped with flat-topped clusters of pink, lavender, and blue disk florets. The clusters are about 1 to 3 inches across. Bloom time is mid-summer to early autumn.

Native to eastern and southeastern US, these flowers attract pollinators such as butterflies, bees, skippers, and parasitic wasps.
