Ecology

Natural habitats of this mat-forming perennial include rocks, cliffs and river-banks, but it also grows in a wide variety of artificial, disturbed and fertile habitats, including spoil heaps, mining waste, paths, roadside verges and urban pavements. It is a common weed of horticulture, especially in lawns, and is a particular nuisance in pots. The plant is tolerant of a wide range of soils and can stand heavy trampling. 0-1150 m (E.
