Groundsel (Senecio vulgaris) is useful plant for rabbits because it has a long growing season and can be found dry crevices, waste ground and on ground that has recently been disturbed. It is palatable and available when other forage is scarce. This picture was taken in March. The plant is sometimes listed as poisonous because it contains small quantities of pyrrolizidine alkaloids, but large amounts would need to be eaten for this to be a problem. Groundsel is difficult to pick in large quantities. There are no reports of toxicity in rabbits.
