Habitat

Found in hedges, wood-borders, scrub, and on rough banks and sheltered sea-cliffs. It is sometimes cultivated in gardens and can occur as an escape in habitats such as roadsides and railway banks. Away from the coast it seems to prefer calcareous soils.

When to see it

In flower during June, July and August.
