Conoclinium coelestinum (previously Eupatorium coelestinum), Blue Mist Flower, Wild/Hardy Ageratum is a herbaceous perennial in the Asteraceae (Aster) family. It is Native to the Central and Southeastern United States and is hardy in USDA zones 5-9. I use all natural and organic growing practices in all of my gardens, I do NOT use any synthetic fertilizers or pesticides. These seeds were open pollinated and harvested in 2024.
💚HEIGHT - 2-3'
💚WIDTH - spreading habit, can form a dense ground cover
💚SUN - Full - Dappled Sun
💚SOIL - Moist - Dry Soils
💚FLOWER - Bluish/Purplish in late summer
💚TOLERATES - Wet soil, Deer resistant
💚BONUS - food source for native bees, butterflies and pollinators
Conoclinium can reach 2' high and can spread to form a dense ground cover. It can live in full sun with sufficient moisture to dappled sun in dry sites. It flowers lovely blueish/purplish flower in late summer to fall. It is an aggressive spreader by rhizomes and self seeding and can be considered a pest. It might be more suitable to a location where it can be left to spread.
It is an attractive plant to bees, specifically native bees, butterflies and pollinators in general. It has many applications for use in the landscape - wildlife garden, erosion control, rain gardens, cut flowers, deer resistant, etc.
I personally loved this plant in my garden, 2021 being the first season. It did really well in a shadey, moist location and added lovely purple color to an otherwise green area. However, I didn't know about it's more aggressive growing tendencies, so I might have to move it to another location.
Again for 2022, I loved this plant - it adds such lovely purple flowers late in the season. I often saw Monarch's feeding on the flowers. Additionally, they held up for such a long time as a cut flowers in a vase. They have overgrown their space and are crowding out the perennials in the are, but I can manage that with all the positives it brings :). In my 2024 garden I pulled a lot of blue mist flower that had travelled outside of its desired location. I transplanted it to other spots on my property.
