Known Hazards: None known Mature Height: 1.5 Mature Width: 1 Habitat: Fields, waysides, waste places, copses etc[17], often on moist soils in shade[4].
Propagation Notes: Seed - sow in spring or autumn in a cold frame[4]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer.
If you have sufficient seed, it could be worthwhile trying an outdoor sowing in situ in the spring.
Division in spring or autumn[111]. Fairly small pieces of root can be used, so long as each piece has a growth bud on it[4]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.
Root cuttings in winter. Cut sections of root about 5cm long, place them in a warm greenhouse over the winter and they should grow away vigorously[4].
