Watering

Moderate regular watering, allowing brief slight drying between soakings

Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

Shorten last year's flowering stems to one or two buds from the older woody framework. Remove thin, weak and dead shoots. Prune in early to mid-spring as growth resumes; avoid winter pruning that exposes new shoots to frost.

Propagation

Propagate by softwood cuttings from stems or basal shoots in early summer. Plants can be short-lived so regular propagation is recommended. As this plant is protected by Plant Breeders' Rights, any propagation should be for personal rather than commercial use

Growing

Thrives in light, moderately fertile, well drained soil in full sun; may need support if grown in richer soils (see staking perennials). Shelter from cold winds in areas prone to frosts. May die back to a woody base in cold winters
