Growing Information
How to plant:

Propagate by seed, cuttings, division or separation - Easy to grow from seed and plants usually flower the first year. Plant in containers in cold frame in spring.

Take basal cuttings in spring.

Divide in early spring or fall.

Maintenance and care:
Deadhead flowers to prevent reseeding and encourage foliar growth and secondary bloom. (Plants are often short-lived, so allowing some reseeding isn't a bad idea.)

Cut back to 6 to 8 inches in late summer to stimulate new growth and help overwintering. Don't prune again until spring clean-up.

Water when very dry.

Divide in spring or fall every 1 to 3 years.
