Native; a perennial Oceanic Southern-temperate herb; restricted to the Atlantic coast from north-west France to north-west Portugal and into Britain. The remaining British population is on coastal slopes in Pembrokeshire.
It is extinct in Cornwall, the last record for Sandymouth, near Bude being just before 1981. Here it was destroyed by the construction of a car park. Also formerly known at Porthgwarra, in west Cornwall, it has not been seen here since 1967, despite repeated searching.
Habitat & Ecology
In Pembrokeshire it grows on the bevelled slopes of coastal cliff in maritime grassland. This is the kind of habitat in which it was formerly found at Porthgwarra.
