Growing Information
How to plant:

Propagate by cuttings, layering, division or separation - Seed of this hybrid is sterile, so it will not self-seed and must be propagated vegetatively.

Divide plants in spring or fall. Make softwood cuttings in early summer.

Maintenance and care:
Plants seldom require division.

Deadheading not necessary to prevent spreading, as seeds are sterile. But may encourage continuous flowering through the season.

Cutting plants back by half to two-thirds encourages fresh foliage growth.
