How to grow

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 best foliage, provide shelter from cold winds; like 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
