How to grow
Cultivation
Grow in a fertile, neutral soil in light or partial shade, and ensure good drainage, especially in heavy soils. This species may be more tolerant of heat and humidity than others, but less tolerant of dry spells, particularly in the growing season. The woody rootstock tends to lift out of the ground over time, so mulch annually to retain moisture. Divide and replant every 3-4 years to maintain vigour
Propagation
Propagate by seed or by division in autumn
