Wild Ageratum or Mist Flower (Conoclinium coelestinum)

Mist flower is ideal for rain gardens and areas where it can be allowed to spread, which it does both by seed and underground stems. Because of the aggressive spreading, it should be used cautiously in formal flower beds.

The flowers are very attractive to bees and butterflies, and a more dense flower display can be achieved by trimming the plants in summer. From a distance, the flowers create an illusion of blue mist. The bitter foliage is usually avoided by deer and rabbits.

Another common name for mist flower is "wild ageratum." It is also now categorized under the genus Conoclinium.
