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.
