A long-lived perennial herb, persisting in old gardens and allotments and spreading by root fragments to roadsides, waste ground, railways, sandy seashores and river-banks. The plant is highly sterile, and seed-set is unknown in our area. Lowland.
A. rusticana was introduced before 1500, initially as a medicinal herb, but by 1650 it had replaced Lepidium latifolium as a vegetable cultivated for hot relishes. It spreads wherever there is cultivation or dumping of soil, but its range now seems to be stable.
Not known in the wild; naturalised throughout temperate Europe, whence it has spread to N. America and elsewhere.
