General description

Erect, perennial herb <1.5m high. Ridged & bristly stems & a creeping rootstock. Dark green leaves, coarsely-toothed & covered in stinging hairs. Long tassel-like clusters of greenish-yellow flowers (Mar-May).

Gardens, waste places, riverbeds, coastal cliffs, rough grasslands. Prefers damp areas of high fertility.

Seed dispersed by birds. Spread locally by creeping roots.

Site management
