Ragwort

Jacobaea vulgaris

Ragwort is instantly recognisable by its golden-yellow daisy-like flowers that appear in large, open clusters. It thrives on Lihou in areas where the vegetation is not overly dense, creating a splash of colour among the grass. Though toxic to livestock, it supports many insects, such as the cinnabar moth caterpillar, which feeds on its leaves.

  • Habitat: Fields, grassland, roadside verges, and lightly disturbed coastal sites.
  • When to See: Bright yellow flower clusters from mid-summer into early autumn.
  • Length: Often 30–80 cm tall, with upright, branched stems.
