A perennial herb of coastal rock crevices and free-draining skeletal soils by the sea. Habitats include cliffs, rocky shores and platforms, spray-drenched shingle, stabilised sand dunes and stone sea-defence walls. The seeds float and retain some viability even after a year in sea water. Lowland.
The distribution of L. scoticum in Scotland is little changed, but there are losses in N. Ireland, some since the 1962 Atlas. Drought sensitivity and the requirement for cold, wet conditions for germination may be important in limiting the southern range of this species in our area.
European Boreo-arctic Montane element; a coastal species also found in E. Asia and N. America.
