An annual or biennial herb of dry, coastal grasslands, sea-bird colonies, sea-walls, upper edges of beaches, sandy waste ground and roadsides. Inland, it occurs on well-drained soils, often, but not always, as an alien. Lowland.
The current distribution of C. tenuiflorus is similar to that mapped in the 1962 Atlas. It is at its northern limit in E. Sutherland and Caithness, but in continental Europe it reaches only the southern tip of Holland. The inland records in England frequently represent wool aliens, but these can be difficult to distinguish from native occurrences.
Suboceanic Southern-temperate element.
