A shortly rhizomatous perennial herb growing in damp shaded places, but also in more ruderal habitats such as quarries, waste ground and rough, grassy places. 0?380 m (Cotterdale, N.W. Yorks.).
Many of the areas in which H. maculatum grows were not well recorded in the 1962 Atlas and its distribution is now much better known. Two subspecies occur in our area, the diploid subsp. maculatum and the tetraploid subsp. obtusiusculum, and these are mapped separately.
Eurosiberian Boreo-temperate element.
