Conoclinium coelestinum, commonly known as blue mistflower or wild ageratum, is a perennial herbaceous plant that belongs to the Asteraceae family. Native to North America, it thrives in various habitats, including meadows, prairies, and along stream banks. The plant can grow up to 3 feet tall and has a spreading habit with numerous branches.

From mid-summer through fall, it blooms with clusters of small blue or lavender-colored flowers that resemble mist. Blue mistflower is particularly attractive to pollinators such as bees, butterflies, and hummingbirds, thanks to its nectar-rich flowers. In addition to its ornamental value, the plant has medicinal properties; traditionally, its leaves have been used to treat respiratory ailments like coughs. This low-maintenance plant prefers moist soil but can tolerate drought conditions once established. It also grows well in both full sun and partial shade.
