Care notes

CultivationGrows 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
PruningCut down to the base in late autumn
PropagationPropagate by division in late autumn or spring or separate root rhizomes when dormant in winter and treat as you would root cuttings
Pest resistanceMay be susceptible to slugs
Disease resistanceGenerally disease-free
