Growing Information
How to plant:

Propagate by seed, cuttings, division or separation - Root cuttings are most successful propagation method. In early spring, make 2- to 3-inch long cuttings (at least .5-inch in diameter). Plant horizontally in well-drained soil.

Sow seeds directly in the garden bed in either spring or fall. Hybrids will not come true from seed.

Maintenance and care:
Keep watered in dry weather, but do not overwater as plants will rot in wet soil.

May require staking, especially in rich soils. Cut back spent flower stems to encourage more bloom.

Self-seeds readily. Deadhead to prevent self-seeding.

To increase the longevity of this short-lived perennial, cut back to the crown after flowering, and divide plants every two or three years.
