It is divided into 2- or 3-branched, fleshy stems, enfolded in a beige, thin layer of bark. Leaves are grey, oblanceolate, sometimes coarsely toothed and are up to 15 mm long. Flowers are bright yellow, in 1 or 2 discoid heads, at branch tips and on short peduncles. Othonna arbuscula flowers in winter and loses it leaves during the summer months. This plant also has a shallow root system for easy water uptake.
