Growing Information
How to plant:

Propagate by seed, cuttings, division or separation - Cuttings are usually more successful than division.

Take softwood or semi-ripe cuttings from early- to mid-summer. Remove the lower leaves and root in sand.

Purchased seed is easy to germinate, but saved seed may not breed true to type.

Maintenance and care:
Cut the plants back severely after flowering to prevent seeding and encourage healthy foliage growth and secondary blooms.

Do not prune in fall. Remove damaged foliage in spring.

Short lived if drainage is poor or weather is hot. Divide every 1 to 3 years.
