An annual to biennial root-hemiparasitic herb of a wide range of base-rich to acidic, moist habitats, including wet heaths, valley bogs, wet meadows, ditches, fens and hillside flushes. Its sites are usually more enriched than those preferred by P. sylvatica. 0-550 m (E. Highlands of Scotland).
The decline of P. palustris in C. & S. England and many parts of Ireland was already apparent in the 1962 Atlas and the species has suffered a further substantial decline since then, mostly through habitat loss due to drainage and agricultural improvement. Elsewhere, there are only local losses.
European Boreo-temperate element.
