It will grow in any soil, in standing water, moist or dry areas and will tolerate full sun and some light shade. Although seeds are sterile, it spreads actively by rhizome. Propagate by division, in the spring or fall. For best results, prune to 15 cm in the summer, when the flowers appear to promote a fall flush. Not suitable for most small landscapes, as it spreads rapidly. Good for stabilizing slopes.
