Devil's claw - yellow-flowered (Ibicella lutea)



Yellow-flowered devil’s claw is a low-growing annual plant to 50 centimetres high and spreading to 1.5 metres wide. It has large round or kidney-shaped leaves and yellow trumpet-shaped flowers with purple spots inside the throat. The woody seed capsules open into pairs of curved horns (10 centimetres long). The weed is spread when the clawed seed capsule attaches to livestock, particularly the feet and heads of sheep (consequently causing injuries).

Infestations occur in isolated patches, often on roadsides and around stock camps. The leaves have an unpleasant odour and are not eaten by stock. Plants will compete with summer crops.

Yellow-flowered devil’s claw is native to America.
