Ragwort in detail
Common Ragwort (Senecio jacobaea L., hereafter referred to as ragwort) is listed as an injurious weed under the Weeds Act of 1959 due to its toxicity to grazing animals, particularly horses and cattle.
Ragwort is normally a biennial, present as a rosette close to the ground in the spring of its first year then growing upwards and flowering during the summer of its second year. However, cutting or topping ragwort may alter the plant's lifecycle and result in it being present as a perennial.
