Growing Information
How to plant:

Propagate by seed, division or separation - Divide in spring or fall. Self-seeds prolifically.

Maintenance and care:
Usually requires staking. Remove faded flowers, or cut back entire flower stalk when mostly faded. Cut before seeds mature to prevent widespread self-seeding. Cut plants back by 1/3 after blooming to encourage compact growth and rebloom. If foliage becomes unsightly after blooming, cut back to basal foliage. Mulch heavily for winter.
