Tracheophyta MagnoliopsidaAsteraceaeSenecioSenecio paludosus


A long-lived perennial herb of tall-herb fens and ditches. The roadside ditch which is now its only native site is usually flooded in winter but dry in summer. Seed-set is poor there, but plants cultivated from material from this site show improved seed-set both in cultivation and at transplantation sites. Lowland.
