How to Grow

Cultivation

Ideally plant in full to light shade in humus-rich, evenly-moist soil. When grown on drier soils the lower leaves are often lost. Mature plants do not transplant well as they have an extensive fleshy root system. They can take several years to settle in the new position

Propagation

Propagate by seed; sow seeds as soon as ripe and keep in cold frame, or sow indoors after four weeks of cold stratification. Take root cuttings in spring or autumn

Suggested planting locations and garden types

  • Architectural
  • Low Maintenance

Pruning

Cut down after frost

Pests

May be susceptible to aphids

Diseases

May be susceptible to honey fungus in gardens where it is present but insufficient data to determine degree of susceptibility
