A scrambling or trailing perennial herb found as an escape or a relic of cultivation in waste and rough places, often by old abbeys or nunneries, and in churchyards, woods and on grassy banks. It spreads by rhizomes. Lowland.
This species was grown for its medicinal properties. The date of introduction is unknown, but it was recorded in the wild from Cambridgeshire in 1685. It is now rarely cultivated, and is gradually declining.
Probably native in S.E. Europe, N. Turkey and the Caucasus, but so widely naturalised in temperate Europe that its native range is obscured.
