Devils Walking Stick – Aralia spinosa is an aromatic spiny deciduous shrub or small tree growing 2–8 m tall, with a simple or occasionally branched stem with very large bipinnate leaves 70–120 cm long. The trunks are up to 15–20 cm in diameter, with the plants umbrella-like in habit with open crowns. The young stems are stout and thickly covered with sharp spines. The plants generally grow in clusters of branchless trunks, although stout wide-spreading branches are occasionally produced.
