How to grow

Cultivation Grow in fertile, moist but well-drained soil in sun or partial shade. If the soil is moist, a shadier position may be tolerated. To prevent the rhizomes rising to the surface, mulch annually and divide every few years ensuring the crown is not buried

Propagation Can be propagated by division; they need to be divided regularly. Lift the plant when in spring growth, taking small vigorous sections from around the edge. Each section should have good roots and 2-3 shoots
