Conoclinium coelestinum | blue mist flower

Blue mist flower, also commonly called hardy Ageratum, is an Eastern U.S. native occurring frequently in New Jersey and regions south and west. Producing tufts of pale blue flowers in the fall, this is a good option for adding a colony of late season color. Topping out at 2’ tall, this is a lower-growing species but it’s quick to spread, both by seed and rhizome. It prefers moist soils and partial shade and is considered aggressive in these conditions so consider the planting location thoughtfully, avoiding use in very small gardens or next to diminutive neighbors. Makes a great cut flower.
