A stoloniferous or rhizomatous perennial herb, which has escaped from gardens and become naturalised on railway and roadside banks, on walls and in churchyards and other grassy and waste places. 0-445 m (Nenthead, Cumberland).
P. aurantiaca was grown in gardens by 1629 and recorded from the wild by 1793. Two subspecies are recognised in our area, subsp. aurantiaca and subsp. carpathicola. Although expertly determined records of these were mapped by Perring & Sell (1968), they have not been comprehensively recorded since then and are not mapped separately here.
P. aurantiaca has a European Boreal-montane distribution; it is naturalised outside this range in Europe, N. America and elsewhere.
