A rhizomatous, perennial herb found only in dry, rocky, maritime heath near Derrynane on the coast of S. Kerry and the Beara peninsula, W. Cork. It was formerly naturalised near the coast in S. England. Lowland.
There has been some limited damage to the Irish population of S. planifolia from housing development, but its distribution appears to be relatively stable overall. Uncontrolled fires have affected some populations, but these may actually favour the species. The English plants may have been imported with Pinus pinaster. They were known in Dorset from 1847 until c. 1914, and in S. Hampshire in 1915.
Suboceanic Southern-temperate element.
