Blue Mistflower prefers full sun to partial shade and moist, well-drained soils. It is quite adaptable and can tolerate a range of soil types, including clay. It can spread aggressively through rhizomes, so it's best to plant it where its spread can be controlled, or in a naturalized setting. Deadheading can encourage more blooms, but it's not strictly necessary. It is generally pest and disease resistant.
