A perennial, moss-like herb which grows in woodland and moist, shaded grassland. It is naturalised in gardens, churchyards and damp valleys near the sea. At Landewednack (W. Cornwall) a population first recorded in 1922 was badly hit by summer drought in 1975 and 1976 but recovered slowly thereafter. Lowland.
S. kraussiana was introduced to cultivation in Britain in 1878 and is often an abundant weed in the shady corners of greenhouses. It was first recorded in the wild in Camborne (W. Cornwall) and Tullaghan (Co. Leitrim) in 1917. It has spread slowly since it was first mapped by Jermy et al. (1978).
Native of C. & S. Africa; locally naturalised in S.W. Europe and the W. Mediterranean region.
