A rhizomatous perennial herb found on waste ground, waysides and banks, and in hedgerows and woods. It is commonly cultivated, and occurs as a casual or, more frequently, as established and persistent populations. Lowland.
C. persicifolia, introduced into cultivation before 1596, was claimed as native when it was found in the wild by Druce (1903), but the evidence for this is very unconvincing. The large increase in records since the 1962 Atlas is probably due to continued escapes from cultivation, as well as to better recording of aliens.
A European Temperate species, absent as a native from much of W. Europe.
