The spreading lignotuberous shrub typically grows to a height of 1 to 2 metres (3 to 7 ft) and has non-glaucous branchlets. It has simple dissected tripartite leaves with a blade that is 80 to 180 millimetres (3.1 to 7.1 in) in length and 20 to 30 mm (0.8 to 1.2 in) wide. It blooms from May to July and produces a terminal raceme irregular inflorescence with yellow or cream flowers. Later it forms rugose ellipsoidal glabrous fruit that is 19 to 35 mm (0.7 to 1.4 in) long.
