Banksia robur, the swamp banksia, is a dramatic looking banksia with large serrated leaves. The new growth has a felty coating of brown hairs, which is an attractive feature. It is naturally occuring in damp areas on sandy soils, but is very adaptable to a wide range of conditions and soils. It needs full sun for best flowering. The flowers are bluish green, and turn yellow green as the flower ages. It is hardy to frosts once established, but may need protection from frosts when young. The plant has few pests and diseases, making it an easy care plant.
