How to Grow

Cultivation

Grows best in a deep, moderately fertile soil that is moist but well-drained, but will tolerate most soils. It needs plenty of space and has the potential to become a nuisance on sandy soils. For the best foliage, provide shelter from cold winds; likes sun but tolerates partial shade

Propagation

Propagate by division in late autumn or spring or separate root rhizomes when dormant in winter and treat as you would root cuttings

Suggested planting locations and garden types

Architectural
Cottage and informal garden
Prairie planting
Low Maintenance
Flower borders and beds
Hedging and screens

Pruning
