Growing Information
How to plant:

Propagate by seed, division or separation - Cultivars must be propagated by division, as they do not come true from seed.

Plants self-seed prolifically but are easy to control. Plant seeds in summer and transplant in fall.

Divide in early spring. Take 3- to 4-inch root cuttings when plants are dormant and root in containers overwinter.

Maintenance and care:
Keep soil moist but not soggy.

Deadhead to prevent reseeding.

If foliage deteriorates in summer, cut to ground to encourage a new flush of growth.

Divide in spring. Division required only every 6 to 10 years.
