NATIVE, AXIOPHYTE
Hairy Rock-cress is a biennial or perennial herb growing in dry, sunny, exposed situations on rock outcrops and in grassland on base-rich substrates, particularly chalk and limestone; also occurring on sand dunes and on bridges and walls (D. A. Pearman in Preston et al, 2002)
In Norfolk, Hairy Rock-cress is most frequent on the chalk soils of the Brecks and the north-west of the county. It was probably always scarcer in east Norfolk but now seems to have almost disappeared.
