    Recording advice

    Unless identified by a recognised expert, a photo is required. Show details of flowers, stipules and calyx.  If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed.


    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.
