A deciduous shrub or small tree. It grows up to 8-10 m high. It has a short trunk. The bark is grey and smooth. The leaves are alternate and compound. The leaflets are curved and sword shaped. They taper to the tip. They are 5-8 cm long. They are thin and light green above and paler underneath. They are more narrow than showy mountain ash. (S. decora). The flowers have petals which are broadest toward the tip. They are 3-4 mm long. They are in dense flat clusters. The fruit are bright coral-red. They are 4-6 mm across. They have thin flesh.
