Blue Mistflower | Plant Profile

Blue Mistflower (Eupatorium coelestinum) are wildflower perennials that are native to the Eastern United States. The foliage is medium green, ovate, and deeply serrated. Large numbers of blue-purple fluffy white flowers top the foliage from mid summer to fall.

Blue Mistflower prefers fertile, medium to wet, well drained soils in full sun to part shade.

Blue Mistflower can be attractive additions to wildflower or pollinator gardens. They are most appreciated in naturalized areas along streams, ponds, or damp woodlands. Do not grow near other perennials as the aggressive roots may interfere with other plants.


Blue Mistflower Characteristics

Blue Mistflower spread aggressively and can be considered invasive in prime conditions. Runners sprout from the base of the plants and occasionally take root where they touch the ground. Blue Mistflower can also propagate via self seeding from spent flowers. If desired, plant division can be an additional form of propagation. If the plants become too tall, they may fall towards the ground. Cut them back in the summer to help to control the height.

There are few serious insect or disease issues that threaten Blue Mistflower. Powdery mildew, miners, and aphids may occur.
