How to grow
Cultivation
Will grow well in fertile, humus-rich, moist but well-drained soil in full sun or partial shade in a sheltered position. Plant in autumn, add fertiliser in spring to promote good growth and mulch avoiding the stem area. Irrigate regularly until the plant becomes established after which it should not require routine watering. See tree peony cultivation for more details.
