Senecio viscosus is a herbaceous annual plant of the genus Senecio. It is known as the sticky ragwort,[1] sticky groundsel[citation needed] or stinking groundsel.[2]


An annual, growing to 70 cm high and covered with glandular hairs. Very similar to Senecio sylvaticus which does not have glandular hairs. The outer bracts show a brown tip. The ray-florets are ligulate, yellow and at first spreading then rolled back. The leaves are alternate and deeply lobed. Senecio vulgaris (Groundsel) does not have ray florets.[3]


Locally common in Britain and Ireland on waste ground.[3][4][5]
