How to grow

Cultivation

The ideal soil is a deep, fertile, well-drained loam but it will grow in most soils and has good drought tolerance. Do not move this plant as new shoots will emerge from deep roots unavoidably left behind and may be difficult to eradicate. Has the potential to become a nuisance if not managed well

Propagation

Propagate by division in spring or autumn or by root cuttings in winter
